摘要:
A feedback control system controls developability of a xerographic imaging device that uses optical sensors for measuring development values based upon a target value. The feedback control system includes a controller device and a feedforward device. The controller device includes an input summing node, a gain device, an integrator and a nominal summing node which are serially connected in communication with each other. The input summing node, the gain device and the integrator are operative in combination with each other to receive and process the measured value and the target value to provide an new corrected actuator value to the integrator summing node. The feedforward device is connected to the nominal summing node and receives and responds to the target value to output a nominal actuator value to the nominal summing node. The nominal summing node combines the new corrected actuator value and the nominal actuator value to provide an actuator value to the xerographic imaging device for controlling the developability of the xerographic imaging device. A method for controlling developability of a xerographic imaging device is also described.
