摘　　要：针对目前基于线性变参数系统的增益调度控制设计中存在的控制结构复杂性问题,提出一种基于回路成形的简单且易实现的增益调度控制结构.在此基础上,提出一个鲁棒增益调度控制设计方法.设计过程首先采用补偿器函数使得被控对象奇异值具有期望的形状,以保证被控对象的性能要求,然后利用小增益定理设计一个鲁棒控制器,得到具有良好性能的、结构简单的鲁棒增益调度控制器.最后针对一个化工过程,说明此方法的有效性.*To solve the controller complexity problem in gain scheduling control based on linear parameter varying (LPV) systems, this paper proposes a gain scheduling control structure that is simple to implement, and presents a robust gain scheduling design method based on loop shaping approach. First, a compensator function is used to shape the singular values of the plant so that the shaped plant has the desired performance, and then a robust controller is designed using the small gain theorem. The final gain scheduling controller is simple and can achieve good performance. Finally, the approach is applied to a chemical process to show its effectiveness.
