文章针对在现代工程领域中应用广泛的传统PID控制器不能满足使系统的给定值跟踪和干扰抑制两方面特性同时达到最优的问题,设计了一种反馈型的二自由度PID控制器。并通过理论推导和仿真实验证明了该系统良好的控制特性,可以使系统的给定值跟踪和干扰抑制能力同时达到最优。
Aiming at the problem that the traditional PID controller widely used in modern engineering can not satisfy both the given tracking and the interference suppression of the system, the two-degree-of-freedom PID controller with feedback is designed. Through the theoretical derivation and simulation experiments, the good control characteristics of the system are proved, and the system can achieve the given tracking and interference suppression simultaneously.
