摘要
针对交流伺服系统存在参数时变、负载扰动等建模困难,以及电机和被控对象的非线性、强耦合性等不确定性因素,利用模糊控制和预测控制各自的优点,将二者结合起来形成了模糊预测控制算法。该算法结合了预测控制的鲁棒性好、控制精度高和模糊控制实时性好的优点,提高了伺服系统的性能。试验结果表明该控制算法是可行和有效的。
The conventional control strategies rest on accurate motor models and parameters. In order to overcome this disadvantage, this paper combines fuzzy control with predictive control to form the fuzzy predictive controller, which makes best use of the robustness of predictive control and the real-time fuzzy control, and the system has highly control precision. The conclusion above is verified by the experiment results.
