Abstract
The present study considers a hybrid controller scheme for theoptimal switching of a moving (or scanning) actuator (MA) for aclass of distributed parameter systems. The proposed hybridcontroller switches both the location and control signal of theactuator at the beginning of a time interval and remains unchangedover the duration of the time-interval. Guiding the MA at certain apriori selected actuator positions at different time-intervals ismade possible by solving a double optimization problem. Thedecision method for actuator switching utilizes an LQR optimal control policy.A numerical example with simulation results is presented.
