In this paper, the state feedback decoupling control for bilinear systems is discussed. The sufficient condition for the existence of decoupling controller and the design procedure are given. A real world example, the headbox control of a paper machine, demonstrates the efficiency of the proposed method.
Performance measures for a class of nonlinear discrete-time system are defined in terms of the eigenvalues and the eigenvectors of the linearized system matrix and an interactive computer-aided design of controller parameters is given. The overshoot and the speed of response are the parameters of an exponential envelope constraining the norm of the states under initial condition perturbations. The...
The optimal control of a class of discrete multivariable nonlinear systems given by: xk+1=a(xk)+B(xk)uk, yk=C xk, is analysed. A closed-loop structure is obtained with the proposed performance index. The addition of numerical integrators to the output error and the design of an optimal control law for the resultant augmented system lead to a very robust control structure. The performance of this control...
