Abstract
This paper presents a high-speed communication and real-time control system for AC servo system. A FPGA-based current control system for AC servo machine is developed to achieve high-performance control. In the communication system, sigma-delta modulation is employed to compress data and to transmit the signal over the transmission channels between the controller and the controlled plant. The current control loop is based on the deadbeat control method, and the space vector method is employed to fire the switches of a PWM inverter. Simulation results show that the proposed system can compensate the possible noise in the transmission channels. In addition, the current controller is implemented in field-programmable gate array (FPGA). The experimental results of current control loop with FPGA-based solutions are also given in this paper.
