中文摘要	The modeling and displacement tracking control of a piezoceramic actuator with complex nonlinear hysteresis was studied. A novel Piezo-actuated Electromechanical Coupling Lumped Parame- ter(PECLP) model was proposed by using the state space function. In this model, the intrinsic dynamic nonlinearity was combined into the piezoceramic stack's hysteresis for the first time, and the dynamics of elastic and motive components within actuator were considered simultaneously. Then, the input-output linearization theory of differential geometry was utilized to deduce a simplified subsystem with linear normal form. By this subsystem, a LQ based nonlinear displacement tracking control system was developed for piezoceramic actuator. In contrast with conventional control system, the computer simulation results show that the developed nonlinear displacement tracking control system exhibits a better tracking precision without static error, and a global optimization of system dynamic capability. Furthermore, the frequency bandwidth is expended by one order of magnitude approximately from 638 Hz to 5 217 Hz at -3 dB, which shows a satisfied high-speed frequency response characteristic.
