โฆ Synopsis
It is shown how a frequency domain criterion can be used to obtain meaningful bounds on the responses of nonlinearfeedbac7~ systems. If the system is rlisturbed by a known input or ?zonsm~ initial condition from its state of equilibrium, bounds are obtained on ouer shoot and settling time as the system returns to its state of equilibrium. The method presented also permits to compute bounds for responses to bounded inputs which do not bring the system to a state of equilibrium. The bounds have a graphical inter.wretattin in the Nyquist+lane which is similar in concept to M-circles for linear systems. This gra~hichical interpretation can be used advantageously in the design nonlinear feedback systems.

This paper presents a computer-aided control engineering (CACE) environment for synthesis of nonlinear and time-varying PID controllers for use with systems that have highly nonlinear plants. The implemented CACE technique is based on a four-step systematic procedure. The nonlinear PID controller de
Following recent works on continuous-time nonlinear H,-control, where connections with game theory and passivity conditions have k e n set, the present paper studies the corresponding problem for discretetime systems. The paper describes sufficient conditions for the existence and the construction o
In this paper we introduce a new method to design control laws for nonlinear, underactuated systems. Our method produces an infinite-dimensional family of control laws, whereas most control techniques only produce a finite-dimensional family. These control laws each come with a natural Lyapunov func
The Modified LJ search method used by Nair[1] to find suboptimal controllers for linear systems is extended to the case of nonlinear systems. To illustrate the method, three numerical examples are discussed.
