چکیده
The position control algorithm for a beltdriven servomechanism of the laser cutting machine is described. High-accuracy position tracking control procedure for system with inherent elasticity due to the low-cost belt-driven servomechanism is derived based on continuos sliding mode technique. The proposed robust position tracking control algorithm was tested by simulations and used in the industrial application of a motion controller for the CNC machine. Simulation and experimental results are reported.

Robust Biaxial Motion Control for Laser Cutting Machine
Abstract A position control algorithm for a beltdriven servomechanism of a laser-cutting machine is described. High-accuracy position tracking control procedure for the system with inherent elasticity due to the low-cost belt-driven servomechanism is derived using sliding mode motion control strategy and Lyapunov design. The control design results in continuos sliding mode control law. It pos...

Design and implementation of robust tracking controllers for linear feed drive high speed machine tools are the primary objectives of this work. Cutting forces and friction forces limit tracking accuracy and their influences are minimised through robust controller design. This paper discusses the design and tracking performances of a traditional cascade and a sliding mode controller for a X-Y m...

متن کاملRobust Adaptive Neural Network Control for XY Table
This paper proposed a robust adaptive neural network control for an XY table. The XY table composes of two AC servo drives controlled independently. The neural network with radial basis function is employed for velocity and position tracking control of AC servo drives to improve the system’s dynamic performance and precision. A robust adaptive term is applied to overcome the external disturbanc...

In this work, a MIMO H. controller for the linear motor machine tool feed drives has been designed to reduce tracking errors induced by cutting forces for end milling. The controller is designed using normalized coprime factorization method for the dynamic model of the linear motor system including constant in-line and cross coupling force gain, since the feedback cutting force can be considere...
