PROBLEMS OF A SPEED_CONTROLLED DRIVE SYSTEM WITH BACKLASH

백라쉬를 갖는 속도제어구동 시스템의 문제점

In a speed_controlled system with cascade control which shows an optimal performance in the linear case, limit cycles can occur due to backlash. The various effects observed can be explained with the aid of the describing function. With a first-order load torque observer these limit cycles can be avoided. Moreover the dynamic performance improves considerably and the range of application of cascade control is extended.
