In this paper, two control strategies are developed to control the piezoelectric inertia-friction actuator (PIFA) systems with a great attention to counter for the thermal effect. The first strategy is to use two controllers: one is the main controller (used to control the actuation) and the other is the auxiliary controller to adjust the contact pressure (used to compensate the thermal effect). The second strategy is to use one controller, which serves for two purposes: to control the actuation and to compensate and the thermal effect. The two strategies are tested in a validated simulator. The result shows that the second strategy is better in terms of control accuracy and hardware cost. This paper may appear to be the first study on PIFA with consideration of the thermal effect.
