Abstract

A method and control system are described for controlling output signals of a system that includes multiple dynamic systems. Each dynamic system receives a different input signal and in response provides different output signal. A first control system generates first control signals to compensate for each output signal based on the difference between the output signal and a reference signal. A second control system generates one or more second control signals based on the difference between the output signals. The second control signal is used to compensate the output signals and/or the first control system compensates the output signals based on the second control signal. The first and second control systems have different closed-loop bandwidths, with the closed-loop bandwidth of the second control system smaller than the closed-loop bandwidth of the first control system.

Dependent claims

A method of controlling output signals of a system including at least a first dynamic system and a second dynamic system, the first and second dynamic systems configured to receive a first and second input signal and output a first and second output signal, respectively, the method comprising:

generating first control signals using a first control system, the first control signals provided to the first dynamic system and the second dynamic system to compensate the first output signal based on a difference between the first output signal and a first reference signal, and to compensate the second output signal based on a difference between the second output signal and a second reference signal;
generating one or more second control signals using a second control system, the one or more second control signals based on a difference between the first output signal and the second output signal;
and
at least one of:
compensating at least one of the first output signal or the second output signal, using the first control system, further based on the one or more second control signals generated by the second control system;
or
providing, using the second control system, the one or more second control signals to at least one of the first dynamic system or the second dynamic system to compensate the first output signal or the second output signal, respectively;
wherein a first closed-loop bandwidth is associated to the first control system,
wherein a second closed-loop bandwidth is associated to the second control system, and
wherein the second closed-loop bandwidth is smaller than the first closed-loop bandwidth.
