开关磁阻电机直接瞬时转矩控制系统主控电路的设计

Design of Main Control Circuit for DITC System of Switched Reluctance Motor

为了改善开关磁阻电机(SRM)转矩脉动的缺点,除了采用直接瞬时转矩控制算法优化外,对控制电路的设计也同等重要。控制电路部分是整个系统的核心,起着十分重要的作用。随着电子技术以及集成电路技术的不断发展,所用的控制器不再是由模拟电路和数字电路拼搭而成,而是采用高性能的运算速度很快的微机控制系统,这样就为实时的、复杂的控制提供了保证,为开关磁阻电机的高精度控制提供了保证。

In order to improve the torque ripple of switched reluctance motor （SRM）, the design of the control circuit is equally important, in addition to the optimization of the direct instantaneous torque control algorithm. The control circuit is the core of the whole system and plays a very important role. With the continuous deveLopment of electronic technology and integrated circuit technology, the controller is no longer used by analog circuit and digital circuit is built and become, instead of using a microcomputer control system for high performance computing speed is very fast, so as to provide real-time control and complex is ensured, which guarantee high precision switched reluctance motor control.
