In this study, we design the permanent magnet synchronous motor (PMSM) drive system using field programmable gate array (FPGA), and adopt variable structure control (VSC) to the current regulation. The system is first modeled with Matlab/Simulink, and the controllers in the system, including the speed PI control and current variable structure control, are hardware implemented by Verilog HDL code....
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,...
Based on the technology of field programmable gate array (FPGA), a realization of fuzzy control (FC) system with radial basis function neural network (RBF NN) tuning is presented to a permanent linear synchronous motor (PMLSM) drive in this paper. Firstly, a mathematic model of the PMLSM drive is defined; then to increase the performance of the PMLSM drive system, an FC constructed by a fuzzy basis...
Electric motors are an integral part of industrial plants with no less than 5 billon motors built worldwide every year. Residential and commercial appliances such as refrigerators and air conditioning systems have been using conventional motor drive technology. The machines in these applications typically have low efficiencies and high maintenance. Brushless DC (BLDC) drives are known for higher efficiency,...
This study presents an adaptive fuzzy controller for linear X-Y table based on FPGA (Field Programmable Gate Array) technology. The linear X-Y table is driven by two PMLSMs (Permanent Magnet Linear Synchronous Motors). Firstly, a mathematic modeled for PMLSM drive is defined. Secondly, to increase the performance of the PMLSM drive system, an AFC (Adaptive Fuzzy Controller) constructed by a fuzzy...
Two new methods to improve the ultra-low speed control performance of ac servo system are described in this paper. One is improved M/T method, which could minimize the influence of speed detection dead time and smooth the measurement. Another is instantaneous speed detection based on constant jerk model, which assumes the rotor jerk is constant at the interval of sampling period. The instantaneous...
This paper presents the development of high fidelity real-time model of a permanent magnet synchronous motor (PMSM) drive, to be used in hardware-in-the-loop (HIL) application. The PMSM model is based on a finite-element analysis (FEA) method and implemented on an FPGA chip. The motor inductances and flux maps are computed from the JMAG-RT finite element analysis software. A 3-phase IGBT inverter...
This study presents a high-performance position controller for permanent magnet linear synchronous motor (PMLSM) drives based on FPGA (field programmable gate array) technology.
