摘要
针对实际工业生产过程中存在的大量串联非线性系统,提出了一种基于紧格式线性化的串联非线性系统无模型自适应控制算法。该算法无需建立被控对象数学模型,仅用输入输出数据来设计控制器,有效避免了非建模动态问题。仿真结果表明该算法具有较强的跟踪性能和鲁棒性。
A model-free adaptive control algorithm for cascade industrial nonlinear system is proposed.The controller is designed only by using I/O data of the controlled system,and the model of the controlled system is not necessary.The impact of the unmodelled dynamics of the process model is not exist.Simulation result shows that the proposed method is an effective algorithm with excellent tracking ability and strong robustness.
