NONLINEAR ROBUST CONTROLLER DESIGN FOR THE STEAM- VALVING SYSTEM BASED ON HAMILTONIAN ENERGY THEORY

提出了利用 Hamiltonian能量函数理论设计非线性鲁棒控制器的方法 ,设计了发电机汽门的非线性鲁棒控制器 ,并且给出了估计干扰抑制增益的一个充分条件 ,所得控制器结构简单 ,易于工程实现。由于在控制器设计中未用到任何线性化方法 ,因而所得控制器充分利用了系统的非线性特性。仿真结果证实了理论分析的正确性与控制规律的有效性。

Based on the Ham iltonian energy theory,this paper designs an explicit nonlinear robust controller for the steam- valving system. One sufficient condition to evaluate the disturbance- attenuation gain under the given control law is also presented in this paper. Since the controller design is based com pletely on the nonlinear dynam ic system without any linearization,the nonlinear property of the dynamic system is well preserved,which presents a new way for nonlinear robust controller design. Simulations have verified the effectiveness of the proposed control law .
