针对有刷直流电机的转速控制,设计一种DSP转速控制器.基于DSP芯片TMS320F28335,以传统的PI控制算法为核心,从硬件电路和控制结构2方面对转速控制器进行介绍,并通过离合器接合性能测试,对比ECAP捕获模块和AD采样模块的优劣,从工程的角度优化和完善转速控制器的设计.结果表明:该方法能优化DSP转速控制器的设计,信号采集精度远远高于单纯的AD采样模块.

Design of Motor Rotary Speed Controller Based on DSP Microprocessor

Aiming at the rotary speed control of brush DC motor, design the DSP rotary speed controller. Based on DSP chip TMS320F28335, taking traditional PI control algorithm as core, introduce hardware circuit and control structure of rotary speed controller. Compare ECAP capture module with AD sampling module through clutch joint performance test. The design of speed controller is optimized and improved from an engineering perspective. The results show that the method can optimize design of DSP rotary speed controller and the signal collection accuracy is much higher than AD sampling module.
