Abstract :
In this paper, the problem of reducing limit cycle behaviour in nonlinear systems with disturbances is expressed as an optimal control problem. This optimal control problem is a generalization of the standard state feedback nonlinear dissipative control problem. One of the features of this formulation is the ability to trade off asymptotic stability requirements and disturbance attenuation. Controllers which solve this optimal control problem are computed using a variable grid finite difference method
