ANALYTICAL DESIGN OF QUASILINEAR CONTROL SYSTEMS

This paper presents a method for adequate transformation of the nonlinear plants and control systems models into quasilinear forms and also analytical methods for the design of nonlinear control systems on the basis of these quasilinear models. The solution of control analytical design problem for the quasilinear model of plants exists, if the controllability functional matrix is non singular. The suggested analytical design methods provide asymptotical stability of the equilibrium point in a limited area of the state space or it’s globally asymptotically stability and also desirable performance of transients. There methods can be applied to design control systems for nonlinear plants with differentiable nonlinearity. Examples of nonlinear control systems design resulted in concrete plants
