This paper investigates the development of a simplified speed control of induction motor based on indirect field oriented control (FOC). An original PI-P controller is designed to obtain good performances for speed tracking. Controller coefficients are carried out with analytic approach. The algorithm is implemented using a low cost Field Programmable Gate Array (FPGA). The implementation is followed by an efficient design methodology that offers considerable design advantages. The main advantage is the design of reusable and reconfigurable hardware modules for the control of electrical systems. Experimental results carried on a prototyping platform are given to illustrate the efficiency and the benefits of the proposed approach.

We present an efficient FPGA based implementation of a dynamic simulation framework for Direct Torque Control (DTC) of induction motors. The merit of the proposed DTC emulation framework lies in that it is completely implemented within an FPGA, and therefore can be easily utilized for exploratory system optimizations. The high performance and low area foot-print of the proposed framework implemented on a Virtex-5 FPGA is the result of several innovative design techniques based on hardware time-multiplexing and the utilization of built-in dedicated floating point IP cores. Our experimental results demonstrate that when FPGAs are utilized as computational cores, the DTC dynamic simulation speed can be improved by almost an order of magnitude compared to a software implementation run in Matlab on a personal computer.

This paper investigates the numerical issue of a discrete-time induction-motor emulator implementation. The stability analysis of the finite-word-length implementation shows a coupling between required word length and the sample rate. We propose specific guidelines to analyze this coupling and to estimate the required data word length for both signals and coefficients of the model. To respect algorithm requirements, an FPGA-based implementation was used for architecture development. The direct torque control is implemented to verify in real time the AC-motor emulator prototype.
