Abstract
The present disclosure provides for an imaging machine having an imaging member including a method for maintaining a toner concentration. The method for maintaining the toner concentration comprises: determining a toner concentration (TC) measurement using a sensor; computing a state estimator output from the TC measurement and a pre-stored estimator gain matrix, K; computing an estimated target state from the state estimator and a pre-stored controller gain matrix, K; computing a duty cycle from the estimated target state, pixel count data, and pre-stored target decomposer output; and, updating the duty cycle by repeating the above method for the next TC cycle.
