FPGA Based Speed Control of AC Servomotor Using Sinusoidal PWM
نویسنده
چکیده
This paper presents a Xilinx Field Programmable Gate Array (FPGA) based speed control of AC Servomotor using sinusoidal PWM technique. Xilinx FPGA is a programmable logic device developed by Xilinx which is considered as an efficient hardware for rapid prototyping. It is used to generate 50 Hz sine wave, the triangular wave and the sinusoidal PWM signals. The sinusoidal pulse width controls the speed of Motor. The proposed control scheme has been realized using Xilinx FPGA SPARTAN XC3S400 and tested using SM115 model Alternating Current (AC) servomotor. The result provides a controllable speed with satisfactory dynamic and static performances.

Repetitive Control Based Pwm Inverter Dead-time Compensation for Ac Servo Drive
AC servomotor speed or current controller based on PI control and/or optimal control, can not eliminate the cyclical fluctuations of speed or current when subject to periodic disturbances. However, repetitive control performs well when the disturbance is cyclical with constant period (frequency). For a PWM (Pulse Width Modulated) inverter driven AC servomotor, a time delay is inserted between t...

In this paper we propose a suitable reference wave for Pulse Width Modulation (PWM) AC Drives. Staircase reference waves whose levels are calculated to eliminate certain harmonics are studied and a certain staircase reference waveform with L levels is constructed. When L is made very large in limit, this staircase waveform approaches a continuous one which is called Quasine (Quasi + Sine). This...
