Abstract :
For an SISO minimum-phase nonlinear system with relative degree one or two, a universal integral controller with nonlinear proportional, integral and derivative gains is proposed. Our analysis proves regional as well as semiglobal asymptotic regulation. Simulation results show that nonlinear gains can be designed to improve overshoot and settling time.
