基于现代控制理论的直流电机控制器的设计

直流电机的控制传统上采用PID算法,为了达到更好的控制效果往往还引入电流环,这将使计算量成倍增加;基于现代控制理论设计的二次型最优控制器效果优秀、算法简单、实现容易、调整方便,由于计算量小,所以可以使用更廉价的处理器,是廉价高性能控制器的首选.

Design of the DC motor controller based on modern control theory

Traditionally,PID algorithm is adopted in controlling DC motor.Sometimes current loop is also comprised in order to achieve better control performance,which makes calculation much huger.In this paper,we bring forward quadratic optimal controller based on modern control theory.This controller has excellent performance,realized easily and adjusted conveniently.The algorithm can be implemented by cheaper processor for its less complexity,and is the better choice in achieving cheap and high-capability controller.
