Abstract
This paper proposes a fully digitized hardware design scheme of a vector-controlled servo controller, which is verified and implemented on one-chip field programmable gate arrays (FPGA), for high-performance servo drives of the permanent magnet synchronous motor (PMSM). This scheme integrates the vector control strategy, the M/T speed measurement algorithm, the PI regulating technique and the SVPWM principle as well as the EDA design methodology, and it will be a good substitute for traditional PMSM drives practice. The realized control IC also contains a standard host communication interface, which enables the on-line configuration for all kinds of control parameters. The actual sample frequencies of the torque loop and the speed loop are limited by the selected FPGA; with respect to the Altera FPGA prototype mentioned in this paper, the two loops can respectively obtain a sample frequency of 40kHz and 20kHz as well as a bandwidth of 5 kHz and 400 Hz. Experimental results indicate that the controller can provide a controllable speed range from 0.2 RPM to 10,000 RPM with satisfactory dynamic and static performances.
