SUPERVISING PROPORTIONAL-INTEGRAL-DERIVATIVE REGULATOR Russian patent published in 2000 - IPC

FIELD: automatic control equipment. SUBSTANCE: device has parallel integration and differentiation circuits, as well as amplifier, which outputs are connected to inputs of adder, which output is designed as input channel of regulator, first, second and third dynamic circuits, as well as first, second and third comparison circuits, which negative inputs are directly connected to regulated parameter channel, while their positive inputs are connected to setting channel through first, second and third dynamic circuits respectively. Outputs of first, second and third comparison circuits are connected to inputs of amplifier, integration circuit and differentiation circuit, respectively. Device design provides optimal processing of setting action and optimal suppression of disturbances. EFFECT: improved quality of regulation, increased functional capabilities. 2 dwg
