Abstract. An algorithm of control over objects under parametric uncertainty, perturbations, and restriction to input signal amplitude is synthesized. A method is proposed for signal formatting in such a way as to ensure the control function to be bounded in a given range. Limiting requirements on parameters of object under control, reference model, and regulator to ensure the control system efficiency are formulated. Results of modeling for the case of linear object are presented.
Keywords: control under uncertainty, limitation on control signal amplitude, compensation of perturbations
