Аннотация:We present a class of controls that provide an effect similar to the one produced
by conventional matching conditions between control and disturbance, but now for a broader
class of systems. This is the class of piecewise-constant functions with varying amplitudes,
generated by approximations of “ideal controls” — linear combinations of delta-functions and
their higher-order derivatives. Such a class allows to calculate feedback controls by solving
problems of open-loop control.
