Build, tune and explain Simulink models for converters, drives, EV powertrains, microgrids and controllers, with results that are documented, repeatable and ready for your thesis or paper.

Simulink is the standard environment for system-level modelling in electrical, electronics, control and automotive research. It is also easy to get wrong: solver settings that hide switching behaviour, controllers tuned by trial and error, or models that run only on one computer. Simulink support from Shodhyantri helps you build models that are correct, stable and explainable.
We support M.Tech and PhD scholars working on control systems, power electronic converters, motor drives, electric vehicles, battery management, solar and wind systems, microgrids and grid-connected inverters. Your proposed method or controller remains your contribution. We help structure the model, choose solvers, tune parameters, compare techniques and present the results clearly.
A research Simulink model usually has three layers: the plant, such as a converter, motor, battery or grid; the controller, such as PI, PID, fuzzy, sliding mode or model predictive control; and the measurement and analysis layer that records waveforms and computes indices like THD, settling time or efficiency. Each layer needs correct parameters and clear organisation into subsystems.
Toolboxes such as Simscape Electrical and Control System Toolbox provide component libraries and analysis tools. Choosing the right solver matters: switching converters often need a fixed-step discrete solver with a small sample time, while average models can use variable-step solvers. We help you choose, justify and document these settings in your methodology.
Subsystems, masks and signal naming make models readable, so examiners and co-authors can follow the logic quickly.
We set solvers and sample times suited to switching or average models and explain why in your methodology chapter.
Proposed and conventional controllers are compared under identical conditions, which reviewers expect in comparison studies.
Component values come from datasheets, design equations or base papers, and are listed in a parameter table.
Waveforms are exported as clean, labelled plots with proper axes and legends rather than blurry scope screenshots.
A walkthrough explains each block so you can modify cases, extend the work and answer viva questions.
Ten stages, each with a clear output. Nothing moves to the next stage until you have reviewed the last one.
— You review every stage first, then decide —
Confirms the model simulates without algebraic loops, warnings or solver errors across planned scenarios.
Checks voltages, currents, speeds and power balance stay within realistic limits for the system.
Verifies stability and acceptable overshoot, settling time and steady-state error under disturbances.
Compares baseline results with the base paper to confirm the model reproduces reported behaviour.
Ensures proposed and reference methods share identical plant, parameters and test conditions.
Confirms parameter tables, solver settings and figures are ready for the thesis methodology.
Every stage is shared with notes explaining what was changed and why. You and your supervisor check it, and the next stage starts only after your go-ahead.
| Common problem | How Shodhyantri helps |
|---|---|
| Using variable-step solvers for fast switching converters without checking results. | Use a fixed-step discrete solver with a sample time small enough for the switching frequency, and justify it. |
| Tuning controller gains by random trial and error without any method. | Start from analytical tuning, such as Ziegler-Nichols or loop shaping, or use an optimisation method you can explain and report. |
| Comparing a proposed controller with a poorly tuned conventional one. | Tune the reference controller properly as well. Fair comparison is the only comparison reviewers accept. |
| Presenting scope screenshots with black backgrounds as thesis figures. | Log signals to the workspace and plot them with MATLAB scripts, using labelled axes, units and legends. |
| Building one huge flat model with hundreds of unlabelled blocks. | Group components into named subsystems and use clear signal names so the model is readable and easier to debug. |
| Ignoring model version compatibility when sharing files. | Note the MATLAB release used and save backward-compatible copies if your lab or supervisor uses an older version. |
A paper sketch of plant, controller and feedback paths saves hours of rearranging blocks later in Simulink.
Define values in an m-file rather than inside blocks. Changing a rating then updates the whole model instantly.
Average converter models simulate quickly and help tune controllers before you switch to detailed switching models.
Use the FFT tool over steady-state cycles, state the fundamental frequency and window, and report settings with results.
Apply load steps, irradiance changes or standard drive cycles to show the controller works beyond ideal conditions.
Labels like Vdc_ref and Ia_meas make logs and plots understandable, especially when you return months later.
Save dated copies before major changes so you can return to a working model if something breaks.
Include solver type, step size and simulation time in your methodology. Reviewers need them to judge your results.
Your work is handled by people who read your field's literature, not by a single generalist.
A PhD-qualified specialist from your field who checks the research logic, gap and contribution.
Handles statistics, models and qualitative coding, and documents every analytical decision.
Improves structure, flow, clarity and academic tone without changing your meaning.
Builds and validates MATLAB, Python, ANSYS or COMSOL work where your study needs it.
Checks grammar, consistency, numbering, citations and the small errors examiners notice.
Applies your university or journal template, reference style and front matter exactly.
Yes. We study the base paper, rebuild the system using its parameters and compare our results with those reported. Once the baseline matches reasonably, your proposed modification or controller can be added and compared fairly.
It depends on the system. Many power electronics and EV models use Simscape Electrical, while controller design often uses Control System Toolbox. We check your available toolboxes first and design the model to work with them.
Yes. Your controller design is your contribution. We help implement it correctly in Simulink, tune parameters, test it under scenarios and compare it fairly with conventional methods.
No. Simulation shows how your method actually performs. If it does not outperform a reference under some conditions, that is a finding worth reporting. We help you test fairly and present results honestly rather than adjusting comparisons.
We build in the MATLAB release you have and test the files before handover. Very detailed switching models can be slow, so we advise on step size and simulation time to keep runs manageable.
We can advise on preparing models for real-time targets and code generation, but hardware work depends on your lab setup. Most of our support focuses on simulation models and their documentation.
Yes. Every delivery includes a walkthrough of subsystems, parameters, solver settings and results, so you can modify the model and confidently answer questions from your supervisor or examiners.
We provide research guidance, statistical analysis, editing, formatting and training support. All research content remains the scholar's own work, in line with UGC and university academic integrity norms. We do not guarantee publication, acceptance, indexing or academic outcomes: journals decide through peer review and universities award degrees.
Share your topic, draft or data. We will tell you honestly what it needs, and what it does not, before you pay anything.
