Precise Position Control of a Pneumatic Servo Table System Consideration Dynamic Characteristics of Pneumatic Servo Valves
The performance of the pneumatic servo systems improved greatly as the pneumatic servo valves became commercially available in the late 1980s. At present, one of the best pneumatic servo valves has a dynamic response of 100 Hz and a spool position accuracy of 2% to the full stroke. By using these pneumatic servo valves, the precise position control by the pneumatic servo system has entered a pr...
متن کاملWavelet Based Iterative Learning Control with Fuzzy PD Feedback for Position Tracking of A Pneumatic Servo System
In this paper, a wavelet-based iterative learning control (WILC) scheme with Fuzzy PD feedback is presented for a pneumatic control system with nonsmooth nonlinearities and uncertain parameters. The wavelet transform is employed to extract the learnable dynamics from measured output signal before it can be used to update the control profile. The wavelet transform is adopted to decompose the ori...
متن کاملFPAA-Based PI controller for DC servo position control system
In this paper, the real-time application is implemented for a DC servo position control system using Field Programmable Analog Array (FPAA) technology. An automatic tuning technique based on relay feedback is successfully implemented for obtaining the dynamics of a plant. A non-iterative tuning formulae is used in order to reduce the control efforts and to obtain the desired position. Results o...
متن کاملPosition Servo Control for a Direct-Drive Actuator Based on Genetic Algorithm
A novel position control strategy for a Brushless DC motor (BLDC) drive is proposed in this paper. Brushless DC motor, which is widely used in the field of Direct Drive servo Actuator (DDA) with superior performance, possesses fast transient response and high accuracy. Nevertheless, there are such uncertainties as unpredictable flow torques and estimated errors of the BLDC model in this system,...
متن کاملRobust Qft-based Position Control of Electrohydraulic Servo System
This paper presents the design of a robust controller using the Quantitative Feedback Theory technique for an asymmetric hydraulic cylinder electro-hydraulic servo system based upon a linear, parametrically uncertain model in which some of the uncertainties reflect the variation of the parameters, and taking the external disturbance into account. After the derivation of a realistic nonlinear di...
