Controller Design by Approximation of Ideal Compensators - A Comparison of Computational Methods

A mathematical formulation /1/ of the classical lead-lag design method leads to the same controller approximation or order reduction problem as it arises in more sophisticated modern design approaches as, e. g., LQG/LTR or IH¿-optimal design if these methods are applied to complex plant models (compare e. g. /2/): Given an ideal, but eventually… CONTINUE READING
