摘要：

In the past, to design controllers for nonlinear systems, the intrinsic nonlinear structures are often ignored or destroyed by linearization or feedback linearization methods. However, these controllers, including PID controllers and even some nonlinear controllers based on feedback linearization, are no longer adequate to accommodate the increasing requirement for improved performances and enlarged operating regions of modern nonlinear control systems. This talk sketches recent progresses indeveloping genuine nonlinear approach for controller designbased on homogeneous system theory. In addition, this talk shows that the new controllers can ensure enhanced performance, improved efficiency, and enlarged safe operating range for several practical systems found in the real world.
