Non-minimum Phase Model of Vertical Position Electro-hydraulic Cylinder for Trajectory Zpetc
Hydraulic actuator has been widely used in industrial applications due to its fast response and capability of moving heavy load. The nonlinear properties of hydraulic cylinder had challenged researchers to design a suitable controller for position control, motion control and tracking control. Based on these problems, we had done a real-time digital tracking control studies on electrohydraulic c...
متن کاملContouring Control of Non-Minimum Phase XY Table System using Trajectory ZPETC
Non-minimum phase (NMP) model is a discrete-time model obtained from small or reducing sampling-time of open-loop input and output experimental data. The classical feed-forward controller design of this model using inverse of the closed-loop transfer function would produce an unstable tracking control. This is due to phase and gain errors that caused by NMP zero. Thus, zero phase error tracking...
متن کاملPerfect Tracking Control with Discrete-time Lqr for a Non-minimum Phase Electro-hydraulic Actuator System
This paper presents a perfect tracking control for discrete-time nonminimum phase of electro-hydraulic servo (EHS) system by adopting a combination of feedback and feedforward controller. A linear-quadratic-regulator (LQR) is firstly design as a feedback controller and a feedforward controller is then proposed to eliminate the phase error emerge by the LQR controller during the tracking control...
متن کاملTrajectory Adaptive Zpet Controller without Factorization of Zeros for Non-minimum Phase System in Application to Real-time Digital Tracking Control of Electro-hydraulic Actuator
Electro-hydraulic actuators are very important tools for industrial processes because they provide linear movement, fast response and accurate positioning of heavy load. Recently, with the research and development of mathematics, control theory and basic theory of hydraulic, hydraulic control technology has been developed and has been widely used in many applications such as industrial automati...
متن کاملPosition Control of an Electro-Hydraulic Servosystem - A Non-Linear Backstepping Approach
This paper studies the control of an electro-hydraulic servosystem using a non-linear backstepping based approach. These systems are known to be highly non-linear due to many factors as leakage, friction and especially the fluid flow expression through the servo-valve. Another fact, often neglected or avoided, is that such systems have a non-differentiable mathematical model for bi-directional ...
