Abstract

This disclosure describes systems, methods, and apparatus for a plasma processing system. A method comprises receiving a reference signal defining target values for a parameter that is controlled at an output within the plasma processing system, obtaining a measure of the parameter that is controlled at the output, and calculating a delay between the target values of the setpoint signal and corresponding actual parameter values achieved at the output. The method also comprises providing, based upon the delay, a time-shifted amplitude error indicative of an error between the target values and the actual parameter values and adjusting at least one actuator, based upon the delay and the time-shifted amplitude error, in advance of when an actual parameter value is desired at an actuator output of the at least one actuator while maintaining the output within a threshold range.
