Robust controller design for actuators under load variation condition

Robust controller design for actuators with variable loads is considered. In order to cope with variations of the loads, a stable factorization approach is applied to design problems of digital controllers for actuators. Using the factorization approach, it is possible to enhance the performance of conventional controllers adaptively with additional loops in the structures. The implementation of the proposed controller to realize high-performance using a microprocessor is discussed.<
