Study on the model feedback control system for a class of non-minimum phase systems

摘要

In the present paper, we examine model feedback control systems (MFCSs). Because MFCS is simple, the MFCS has been applied in many applications such as the trajectory control of robot manipulators, serially connected water tanks, etc. The control structure of the MFCS is limited, but Yamada and Moki reported about whether or not MFCS can represent all of the stabilizing controllers of a minimum phase plant. However, no research has been reported whether or not MFCS can represent all of the stabilizing controllers of a non-minimum phase plant. The purpose of the present paper is to give a solution to the question as to whether or not all of the stabilizing controllers for a plant are expressible in the MFCS structure. The relation between MFCS and the parameterization of all stabilizing controllers for a class of non-minimum phase plants is shown. A simple design method to specify control characteristics is also presented.
