ABSTRACT:
A control system provides an improvement in the stability and immunity to noise characteristics without degrading performance of the circuit by including a multiplier circuit that is purposely made nonlinear. A parameter K of the multiplier circuit is not a fixed value, but varies as a function of the error signal amplitude that is applied to one of the two inputs of the multiplier circuit. Advantageously, the parameter K of the multiplier circuit decreases when the amplitude of the error signal input thereto decreases.
