In this paper, a motion control IC for linear motor drive X-Y table using FPGA (Field programmable gate array) technology is presented. Firstly, the mathematical model of the X-Y table is defined. Secondly, an adaptive fuzzy controller (AFC) is introduced and adopted in position loop of X-Y table to improve the motion tracking performance under unmodelled uncertainty condition. Thirdly, in implementation,...
This paper presents a servo system for linear X-Y table, which is driven by two permanent magnetic linear synchronous motors (PMLSMs), based on a TMS320F2812 DSP controller. In this proposed system, the fully digital servo controller for each PMLSM and the trajectory motion controller for X-Y table are all implemented by a DSP chip. That is, the detection of quadrature encoder pulse (QEP), coordinate...
A FPGA-based servo control IC for use in a permanent magnet linear synchronous motor (PMLSM) drive is presented in this paper. Mathematic model of the PMLSM is presented and the vector control scheme is used in the current loop of the PMLSM drive. Then, to increase the performance of the PMLSM drive, an adaptive fuzzy controller (AFC) constructed by a fuzzy basis function and a parameter adjustable...
