基于Matlab无速度传感器异步电机矢量控制器的建模与代码生成

Modeling and Code Generation of a Speedless Sensor Vector Controller for Induction Motors Based on Matlab

使用基于模型的开发流程设计无速度传感器异步电机矢量控制器。在M atlab/S imu link中进行系统级设计,对速度控制模块、前馈解耦PI电流控制模块、自适应磁链观测器等控制器模块进行建模并整合仿真。模型验证无误后,加入C281x芯片支持模块,利用Real-Tim e W orkshop从S imu link模型生成DSP的C语言程序。程序的正确性在DSP目标板上得到了验证。

By using model-based development process, a speedless sensor vector controller for induction motors has been designed. A system-level design is performed in Matlab/Simulink environment. The functional blocks of controller, such as speed control block, PI current control block with feedforward decoupling, adaptive flux observer block and so on, have been modeled and joined into an integrated simulation. After correctness of model has been validated, C281x chip support blocks are added. Then C programs for DSP can be generated from the Simulink model by using Real-Time Workshop. The programs work well on target DSP system.
