摘　　要：研究了基于环路成形H∞控制的多变量系统控制器设计。为了能方便地在实际工程中实现复杂的控制,提出了采用多变量PID控制器逼近所得高阶控制器的方法,并给出了如何选择影响闭环系统性能的预补偿器方法。仿真结果表明,文中所得的多变量PID控制器具有较好的鲁棒稳定性和鲁棒性能。最后针对该设计方法,以Matlab6.2为平台开发了一套交互式的多变量系统控制器设计软件MCSLab。Controller design for multivariable processes is studied based on Imp-shaping H∞ control. In order to implement the complex H∞ controller, a method to reduce it to a multivariable PID controller is proposed. A method to choose the precompensator that determines the performance of the closed-loop system is put forward. Simulation shows that the designed multivariable PID controller has good robust stability and performance. MCSLab-software for controller designing of multivariable processes is proposal.
