摘要：

A multimodel controller design procedure based on robust LQ design is evaluated for a highly nonlinear chemical process. The procedure is combined with two gain-scheduling methods: a fixed robust controller with scheduled output gain, and complete scheduling of locally optimal controllers. The performances obtained with the fixed controller, the gain scheduled controllers and conventional PID control are compared and tested on a simulated pH neutralization process.
