摘要
抖动和鲁棒性是滑模控制最显著的特点,在保持系统鲁棒性基础上有效地控制系统的抖动是将滑模控制引入实际应用的关键.在水轮发电机组非线性模型的基础上,将滑模控制引入水轮发电机组的控制,先对水轮发电机组非线性模型进行坐标变换和反馈线性化,然后对一般滑模控制算法进行改进,通过选取合适的滑动模和趋近律,有效地克服了系统的抖动,从而使系统获得较好的控制品质.仿真试验表明本方法十分有效.
Chatter and robustness are the obvious characters of the sliding mode control; how can the chatter of plant be controlled efficiently and its robustness be remained is a key problem about its application. In this paper, the sliding mode control has been conducted into the design of the hydraulic generator＇s controller based on its nonlinear model. First, we exert coordinates transform and feedback linearization on the hydraulic generator nonlinear model, then improve the algorithm of general sliding mode control by selecting appropriate sliding mode surface and reach law, the chatter of the control system has been overcome and better qualities has also been achieved. The simulation has proved this method is very efficient.
