【Abstract】 A dynamic control model for piezoelectric actuators was presented. The control model is stated by pan-Boolean algebra symbol through a series of control rules depending on control practice of piezoelectric actuators. Combining with PID controller, off-line simulation with Rule and PI control was conducted in piezoelectric actuators based on the control model. The simulation results prove that the proposed control model is simple in structure, and easy to be controlled and realized.更多还原
