In contrast to electronic systems that process signals and data, power electronics processes substantial amounts of electrical energy. Over the course of several decades, the field has evolved significantly.
MATLAB can help you to understand the field because it integrates computation, visualization, and programming in an easy-to-use environment where problems and solutions are expressed in a familiar mathematical notation.
You can use MATLAB® and Simulink® to:
- Reduce project time by 50% by simulating and generating code for supervisory and closed-loop control algorithms instead of traditional hand coding and testing on hardware.
- Access thousands of ready-to-use electrical modeling components and examples for desktop simulation.
- Use add-on toolboxes for control design, fixed-point design, signal processing, and certification.
- Get real-time simulation support for Speedgoat and other real-time hardware platforms.
- Generate ANSI C and processor-optimized C and HDL code for multiple leading microcontrollers, FPGAs, and SoCs.
Simulink for Power Electronics Control Design
Build and Tune Motor Control Algorithms
Build accurate system models using MATLAB and Simulink by using libraries of motors, power electronics, sensors, and loads. Explore the full potential Bode plots and root locus as well as other classic linear control design techniques. The inverter power electronics that regulate voltage and frequency can be controlled via automated PID tuning.
To design current and speed controllers, you can use Simulink to run closed-loop simulations under normal and abnormal operating conditions. To ensure safe motor operation, design fault detection and protection logic for model starting, shutdown, and error modes, as well as derating and protection logic.
Design Digital Control for Power Converters Faster with Simulink
Simulate analog and digital components in the same environment with Simulink. Evaluate and verify design choices before implementing the controller with closed-loop simulation of the power stage and controller.
Model power converters at different levels of fidelity. Using AC frequency sweeps and system identification, perform small signal analysis on switching converter models to obtain linear models. Classic control techniques (Interactive Loop Shaping with Bode, Root-Locus Plots) are possible with these models.
Develop Battery Management System Software with Simulink
Simulate electronic circuitry and battery pack models with lumped parameters. Work with models that have equivalent RC circuit battery packs models, switching power electronics, and varying loads and environmental conditions. Design, tune, and test supervisory, closed-loop, and fault-detection algorithms with Simulink.
Usingtest data, tune battery model parameters and capture cell chemistry, thermal, aging, and other nonlinear characteristics. State observers are designed for state-of-charge (SoC) for cell balancing and state-of-health online estimation.
