PSO Based Parameter Identification of Colman- Hodgdon Hysteresis Model of a Piezoelectric Actuator and PID Feedback Controller

چکیده
In this paper, a dynamic model of a piezo-actuator based on Coleman-Hodgdon (C-H) hysteresis model is considered. The hysteresis model is established by identification considering the particle swarm optimization (PSO) technique. The identified model is tested considering a classical PID controller in order to achieve a tracking control of nano-positioning system driven by piezoelectric actuator. Experimental results through real-time implementation are presented and discussed. A good system performance was obtained with a tracking error less than 100 nm.

Experimental Hysteresis Identification and Micro-position Control of a Shape-Memory-Alloy Rod Actuator
In order to exhaustively exploit the high-level capabilities of shape memory alloys (SMAs), they must be applied in control systems applications. However, because of their hysteretic inherent, dilatory response, and nonlinear behavior, scientists are thwarted in their attempt to design controllers for actuators of such kind. The current study aims at developing a micro-position control system ...

Piezoelectric-driven stick slip actuators have been drawn more and more attention in the nanopositioning application due to the high accuracy and theoretical unlimited displacement. However, the hysteresis of piezoelectric actuator (PEA) and the nonlinear friction force between the endeffector and the stage make control of piezoelectric-driven stick slip actuator challenge.
