AC Motor SPWM Speed Control (MATLAB Simulation)

AC motor SPWM speed control is a widely used motor regulation method that enables stepless speed adjustment with advantages including high precision, excellent stability, and low noise characteristics. This technique controls motor speed by modifying both the amplitude and frequency of the AC power supply voltage. Through MATLAB simulation of AC motor SPWM speed control, engineers can gain deeper insights into the working principles and benefits of this technology, providing valuable references for practical applications. The simulation process typically involves parameter configuration using MATLAB's Simulink environment, model construction with Power Systems toolbox components, and subsequent analysis of simulation data through scripting functions like 'sim' and 'plot'. Key implementation aspects include carrier wave frequency setting, modulation index adjustment, and inverter bridge configuration using IGBT blocks. Pre-simulation requirements include parameter setting and model construction, followed by analysis and processing of simulation data using MATLAB's data processing工具箱. In summary, SPWM speed control represents a highly effective motor regulation technology worthy of further research and application, with MATLAB providing an ideal platform for algorithm validation and performance optimization through its built-in power electronics and control system libraries.
