摘要

The problem studied in this investigation is how to design and analyze feedback control systems in which a saturation type nonlinearity, or limiter, occurs on the input to the controlled system, or "plant." The plant is assumed to have one input and one output and to be describ-abl3 by linear differential equations with constant coefficients. The scope of the investigation covers plants whose transfer functions are of first to fourth order.nAs a result of the assumption of linearity and the fact that limiting has no effect for small signal inputs, the feedback control system can be designed by the use of conventional, linear feedback, control theory for the small input signal range. The problem then becomes how one can analyze the response of the system for large signal inputs which cause saturation and how to design compensating nonlinear functions which will improve the response should the analysis show this to be necessary.
