Abstract :
A new generic optimal controller structure and regulator design method for linear systems are combined to form an iterative regulator refinement scheme, where the identification and control errors are identical. It is shown how a real nonlinear actuator limiting the amplitude of the control signal influences the control performances. Then the special modification of the original iterative scheme is presented, which allows the user to find the reachable maximal bandwidth by an iterative redesigning the original not reachable requirements. The effectiveness and usability of this new method is demonstrated by simulation examples.
