Dual loop PID configuration

摘要: The proportional-integral-derivative controller produces a process control signal in response to variable and setpoint signal. is subtracted from the produce difference signal, representative of derivative produced. In an inner loop are amplified by respective adjustable gains. outer gains integrated. integrated signals combined applied another gain outer-loop output setpoint, signals, finally affect input/output characteristics sensitivity perturbations. Also, adjustment through does not change that have been previously adjusted means after having set equal zero.
