摘要
The effect of unmodeled fast actuator dynamics on the output feedback stabilization of feedback-linearizable systems is studied. It is shown that if the actuator dynamics are sufficiently fast, the output feedback controller will stabilize the origin of the actual system. Moreover, it is shown that the actuator dynamics need not be faster than the observer dynamics. Copyright (C) 1996 Elsevier Science Ltd.
