  • Control system
    Patent number: 4197577
    Abstract: A control system of the non-linear type which behaves in a substantially `proportional` manner. The system comprises an error detector which compares the input and output of a plant to obtain an error value, and a control unit which derives from the error value a continuous control signal for the plant. The control signal comprises a linear term which is a linear function of the error signal and a nonlinear damping term which is a continuously variable function comprising the ratio of the rate of change of the error signal and the error itself.
