<p>PURPOSE: To facilitate the improvement of the stability and responsiveness of a control system because a stabilizing compensator has a characteristic which is displayed by a specified expression, and acts so as to cancel the peak of the resonance frequency of a resonance system and to improve the stability and responsiveness of the control system. CONSTITUTION: A stabilizing compensator represents the characteristic P(S) of a practical control object by a model showing characteristic Pn (S) similar to the characteristic P(S) and obtains conditions where a sharp peak does not occur at the resonance point on the above represented model for composing itself. For this reason, a pole zero counterbalance into which input having reverse characteristic is added is carried out. Namely, to the characteristic P. (S) of a similar model of the control object shown by a prescribed formula, the characteristic C(S) of the stabilizing compensator is defined as follows; C(S)=(CS<2> +a1 S+a2 )/(S<2> +b1 S+b2 ). In this formula, S is Laplace transforming element; a1 , a2 , b1 , b2 are parameters determined by the resonance frequency of a resonance system. Thus the peak value of the resonance system is removed, and discrepancy in phase is compensated.</p> |
