Abstract :
We consider a single-input single-output minimum-phase nonlinear system which has a well-defined normal form. To improve the transient performance, universal integral controllers with nonlinear integrators are proposed. We prove regional stability as well as semiglobal results. Simulation results are presented showing the improved overshoot and settling time.
