无模型控制律的一种改进算法

针对基本形式的无模型控制律没有充分利用输入输出数据包含的信息,利用输入输出数据的高阶信息,提出了一种新的控制准则函数,推导了其控制律算法.然后针对一类具有积分环节的被控对象设计了带反馈环节的无模型控制器.并在相同条件下,对分别采用基本算法和改进算法设计的无模型控制器进行控制性能仿真研究.仿真结果表明:改进的无模型控制律算法表现出优良的控制品质,跟踪性能良好,具有参数自适应性.该算法适合处理参数时变、结构时变的非线性系统的控制问题.

Research of an Improved Model-free Adaptive Control Algorithm

Owe to the ordinary model-free adaptive controller is not using the system's input/output data sufficiently.This paper utilize the high order of input/output data,gave a new criterion function,and deduced its control law.Then a model-free controller with feedback loop for a class integral system is advanced.Under the identical conditions,two different model-free adaptive controllers are compared through simulations.The results of simulation indicate that the performance of Improved Model-Free Controller is ...
