Dynamic Surface Control

This chapter presents a new method of analyzing the stability of a class of nonlinear systems by using the DSC design approach. It is shown that the closed-loop error dynamics can be described by linear error dynamics with bounded perturbation terms that are a function of the error. The desired eigenvalues of the linear part can be assigned by choosing the control gains and filter time constants. Furthermore, based on quadratic stability theory, feasibility of the fixed controller gains for quadratic stabilization and tracking can be tested by solving a convex optimization problem.
