ABSTRACT
In this book, we have introduced a number of approaches for designing self-tuning
PI/PD/PID controller for nonlinear systems. The main contents can be summarized
as follows:
• In Chapter 3, a PI control with self-tuning gains is presented for a class of single input single output (SISO) nonlinear system. In order to help understand the
proposed method, the controller design starts with the first-order nonlinear
systems, and then extends to high-order systems. The developed PI control
ensures the stable tracking of nonlinear systems. Meanwhile, rigorous stability
conditions for nonlinear systems under the proposed PI-like scheme are
established. It is shown that the derived PI-like control exhibits fault-tolerant
capability without the need for FDD/FDI and transient performance is ensured
despite system nonlinearities, modeling uncertainties, and actuation faults.
