摘　　要：针对橡胶坝充排水这一变结构、大滞后、非线性实际控制系统,提出采用能满足系统稳定性和鲁棒性要求的分数阶PIλDμ控制策略对其进行恒流控制。首先建立了橡胶坝充排水系统的数学模型,从理论上证明了分数阶PIλDμ控制器对于该系统具有较好的鲁棒特性。然后把该分数阶PIλDμ控制器数字化后应用于橡胶坝充排水实际系统中,取得了较好的控制效果。最后给出了恒流量充水过程的实际控制运行曲线,表明本文PIλDμ控制器具有较强的抗干扰性和较好的鲁棒性,达到了恒流量充排水控制的设计目标及要求。Water filling and drainage system is a typical nonlinear, time varying, variable structure system. A fractional order PIλDμ control scheme for such system is proposed. First, the mathematical model of the water filling and drainage system of a rubber dam is established. It is proved in theory that the fractional order PIλDμ controller has better robust properties for the system. Then a fractional order PIλDμ controller is designed for the system in a practical project, which achieves good control effect. Finally, an actual control curve of constant current is given using the fractional order PIλDμ controller. Practice proves that the proposed control scheme is efficient and the system possesses good static and dynamic performance and certain robustness.
