摘要

A mixed H_2/H_∞ approach provides a framework to integrate optimal performance and robustness into a single controller. It has both favorable frequency performance and time domain performance. However, it is a very hard to design and solve the mixed H_2/H_∞ controller. In this paper, we formulate the mixed H_2/H_∞ problem into three independent parts: summarize the state space description of generalized plant, design the output feedback control law and solve mixed H_2/H_∞ optimal controller. Thus, the mixed H_2/H_∞ problem is simplified greatly. Based on these parts, simulation platform of mixed H_2/H_∞ control (SPMC) is developed by Matlab/simulink. Further, We design the mixed H_2/H_∞ controller of load control system of thermal power units by SPMC. Simulation results show that the control system has good performance.
