Abstract
A decentralized control of decoupled plants which each include a motor and a load. A controller is connected in series with each decoupled plant. An adder is configured to receive a set point signal and a negative feedback signal from the plant output and generate an error signal. Each controller receives a set of tuning parameters, modifies the error signal based on a tuning parameter space vector and generates drive signals which actuate the motor, operate the load, and generate the plant output in accordance with a frequency domain assessment function. A compensator samples the error signals and the plant outputs, Fourier transforms the error signals, generates the tuning parameter space vector, based on a frequency domain assessment function, obtains the set of tuning parameters from the tuning parameter space vector, and transmits the frequency domain assessment function and the set of tuning parameters to each controller.
