摘要

Traditionally DC motors are used in applications, which require high performance and accurate control of torque. Recently, AC motors control has been developed to meet the demand for accurate torque control. Especially DTC (Direct Torque Control) techniques incorporating fast microprocessors and DSPs have made possible the high-performance applications of AC motors. In this paper the DTC algorithm implemented in affordable FPGA with use of relatively simple tools, is presented. Direct-Torque-Control is a model-based control. Direct torque is achieved by direct and independent control of the flux linkages and electromagnetic torque. These are obtained through the selection of optimal inverter switching which gives fast torque response, low inverter switching frequency, and low harmonic losses. The paper presents the DTC design (fast control loop T < 5μs) and the interface of the wider motor control system, everything implemented on a single chip (SPARTAN II 50k gates, XILINX's FPGA circuit).
