A Robust Control Algorithm for Tracking the Command Signal with Compensation for the Parasitic Effect of External Unbounded Disturbances

摘要

An output control for tracking the command signal from linear parametrically uncertain systems under external disturbances is studied. The control scheme is simple in realization and of small size, which distinguish it from other known analogs. A numerical example is given to illustrate the performance of the control algorithm. This paper is the continuation of [1] on the design of an output control algorithm (i.e., without any measurement of the coordinates of the state vector or derivatives of the output) for tracking a linear parametrically uncertain linear system by a command signal. Unlike in [1], our results aid in using the control circuit (a serial compensator) of [1] for tracking under unbounded disturbances.
