直接转矩控制交流调速系统转速调节器的设计研究

Research on the Apeed Regulator in Direct Torque Control Variable Speed System

随着直接转矩控制等高性能控制技术研究的深入与成熟,交流电气调速系统正在逐步扩大其应用领域。交流调速系统往往要求对转速实施闭环控制,这是通过转速PI调节器实现的;但是,转速调节器中的比例常数与积分常数基本上仍通过试凑法确定的,这无疑浪费了大量的时间和精力。文章基于理论推导和工程化设计方法研究了两种参数设计方法,给出了MATLAB中的仿真结果,仿真结果表明工程化设计方法更为有效。

With the further study of the advanced control strategy like direct torque control, the ac adjustable speed system is applied in more and more industrial fields. Proportional and integral regulator is often adopted as the speed regulator in most applications. The parameters of PI regulator are often decided by the try and error method and this process takes much time and energy. In this paper two methods are studied which are the theoretical design method and the engineering design method. Two methods are simulated in the MATLAB. The simulation results show the engineering design method is simpler and more efficient.
