该文给出了一种生成优化参考输入信号的学习方法,通过迭代学习产生的参考输入信号能使系统响应跟踪希望响应.在异圆加工中的仿真研究验证了这种方法的有效性和实用性.“,”Many repetitive operations require a control system that has a desired response for a finite time interval. It is required to generate a reference signal so that the response is able to track the desired response perfectly. In the paper, a learn algorithm, which can generate optimal reference, is presented. The algorithms is an iteration process. The application study, which simulates the non-circular machining, shows that the method of the generation of the optimal reference is effective and practical.
