Tracking control of piezoelectric actuator using adaptive model.
Piezoelectric actuators (PEAs) have been widely used in micro- and nanopositioning applications due to their fine resolution, rapid responses, and large actuating forces. However, a major deficiency of PEAs is that their accuracy is seriously limited by hysteresis. This paper presents adaptive model predictive control technique for reducing hysteresis in PEAs based on autoregressive exogenous m...
متن کاملBio-inspired bending actuator for controlling conical nose shape using piezoelectric patches.
In this paper, a bio-inspired bending actuator was designed and fabricated using piezoelectric patches and cantilever-shaped beam for controlling nose shape. The aim of this study is to investigate the use of the bending actuator. PZT and single crystal PMN-PT actuators were used to generate translational strain and shear stress. The piezoelectric patches were attached on the clamped cantilever...
متن کاملLEAD-FREE BNKT PIEZOELECTRIC ACTUATOR
An actuator is a device that converts input energy into mechanical energy. According to various types of input energy, various actuators have been advanced. Displacement in the electromagnetic, hydraulic and pneumatic actuators achieve by moving a piston via electromagnetic force or pressure, however the piezoelectric actuator (piezoceramic plates) displace directly. Therefore, accuracy and spe...
متن کاملActuator State Based Adaptive Motion Drive Algorithm
A new Actuator State Based Adaptive (ASBA) motion drive algorithm was developed. In contrast to classical motion drive algorithms a subset of the motion drive parameters are time varying. The ASBA algorithm uses the steepest descent algorithm to adapt these parameters to minimize a pre-defined cost function. The cost function contains penalties on motion cue errors, simulator motion, and the di...
متن کاملTracking Control of Hysteretic Piezoelectric Actuator using Adaptive Rate-Dependent Controller.
With the increasing popularity of actuators involving smart materials like piezoelectric, control of such materials becomes important. The existence of the inherent hysteretic behavior hinders the tracking accuracy of the actuators. To make matters worse, the hysteretic behavior changes with rate. One of the suggested ways is to have a feedforward controller to linearize the relationship betwee...
