<P>PROBLEM TO BE SOLVED: To improve the responsiveness of a control system where a primary delay element exists in a speed control device and of which controlled object is a 2-inertia resonance system, by measuring a vibration frequency of the controlled object and composing an observer by adjusting and setting various parameters on a real device. <P>SOLUTION: The speed control device is equipped with the observer 6 which comprises: an observer object device 8 which has an equivalent rigid body model 7 on a front side with an assumption that the controlled object is a rigid body, and a primary delay element model 8 on a rear side which are connected serially and outputs an input to the primary delay element model 8 as a speed feedback signal; a subtractor 13 to reduce the speed of the controlled object by an output of the primary delay element model 8; an observer compensator 9 to input the value of subtraction; and an adder 14 to add an output of the observer compensator 9 to an output of a PI controller, and input the added value to the equivalent rigid body model 7. <P>COPYRIGHT: (C)2003,JPO |
