Abstract

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 will discuss new perspectives in handling nonlinear systems and sketch recent progresses in nonlinear controller design including finite-time control, nonlinear observer, domination approach, and sampled-data control. In addition, these talk shows that the new controllers can ensure improved performance and easier implementation for several practical systems, such as marine surface vehicles, electric vehicles driven by in-wheel motors, and hydraulic turbine systems.
