Structually stable multivariable finite settling time control system including nonlinear elements in feedforward path is designed. When nonlinear elements are not included, preservo compensators with all poles of reference inputs are included in front of the controlled objects by internal model principle and control devices are designed to be internally stable. When nonlinear elements exist in front of preservo compensators and controlled objects, control system is designed as finite settling time control is realized adding the disturbances to the linear system. In spite of the small errors of parameters of controlled objects and control devices, and the disturbances, the error between the reference inputs and outputs converges to zero as time passes. The differences between input and output of nonlinear element are added to the output of preservo compensator and controlled object through model of them as disturbances. Then nonlinear system becomes as same as linear system.
