Rate-dependent inverse hysteresis feedforward controller for microsurgical tool
This paper presents the development and initial results of a controller based on a novel rate-dependent hysteresis model. The controller has been developed for “Micron,” a microsurgical instrument designed to sense and actively cancel tremor and other undesired motion during vitreoretinal intervention. To accomplish this, Micron uses a three-degree-of-freedom parallel manipulator with piezoelec...
متن کاملAccuracy Evaluation of Generalized Prandtl-Ishlinskii Model in Characterizing Asymmetric Saturated Hysteresis Nonlinearity Behavior of Shape Memory Alloy Actuators
Prandtl-Ishlinskii (P-I) model is one of the powerful operator-based phenomenological models which is used in modeling complex hysteretic nonlinear behavior in piezoelectric, piezoceramic, magnetostrictive and shape memory alloy actuators. The most appealing and unique aspect of the Prandtl-Ishlinskii model comes back to this fact that this model is analytically invertible and therefore could b...
متن کاملH∞ control for a smart micro-positioning system with an analytical model for the output of the inverse compensation
An experimental study was carried out on a piezoelectric actuator in order to explore the benefits of a mathematical formula [1], that describes the output of the inverse compensation when an inverse Prandtl-Ishlinskii hysteresis model is applied as a feedforward compensator. The inverse Prandtl-Ishlinskii was first formulated and applied for compensation of hysteresis nonlinearities of a piezo...
متن کاملModeling and Identification of the Rate-Dependent Hysteresis of Piezoelectric Actuator Using a Modified Prandtl-Ishlinskii Model
Piezoelectric actuator (PEA) is an ideal microscale and nanoscale actuator because of its ultra-precision positioning resolution. However, the inherent hysteretic nonlinearity significantly degrades the PEA’s accuracy. The measured hysteresis of PEA exhibits strong rate-dependence and saturation phenomena, increasing the difficulty in the hysteresis modeling and identification. In this paper, a...
متن کاملNon-linear control of a hydraulic piezo-valve using a generalized Prandtl- Ishlinskii hysteresis model
Abstract The potential to actuate proportional flow control valves using piezoelectric ceramics or other smart materials has been investigated for a number of years. Although performance advantages compared to electromagnetic actuation have been demonstrated, a major obstacle has proven to be ferroelectric hysteresis, which is typically 20% for a piezoelectric actuator. In this paper, a detaile...
