This article provides a hardware implementation of torque and flux estimators for direct torque control (DTC) of an induction motor (IM) on the Field Programmable Gate Array (FPGA). Due to its high processing frequency, the FPGA circuit presents an alternative strategy for achieving a high performance DTC implementation. This cannot be achieved by Digital Signal Processing (DSP) or Microcontroller application. Optimized hardware architecture is also proposed for implementation of a complete estimator with explicit determination of all the quantities such as the flux phase, the flux amplitude and the torque amplitude. This work presents a precise hardware estimator of the torque and the flux, it developed with negligible estimation error (0.0002 [Wb] RMS estimate error for the stator flux and 0.0005 [Nm] RMS estimate error the torque), in addition to that this estimator is implemented on the Virtex-4 FPGA board with minimal resources(less 5% of slices registers, 5% of DSP48Es and around 17% of LUTS). This estimator is developed and synthesized independently of the command and can be reused for any task which requires the estimation of these quantities. After this the estimator was used to complete a DTC control in a hardware co-simulation procedure with the Xilinx system generator and MATLAB/SIMULINK tools on the Xilinx ML402 development kit.

“…High-performance vector control (VC) strategy in induction motor (IM) drives [1]- [3] can be replaced with pulse-width-modulation (PWM) integrated direct torque control (DTC) strategy [4]- [6]. Parameter tuning, stability analysis and design of proportional-integral (PI) or proportional-integral-derivative (PID) controllers require complicated techniques [7]- [10].…”

“…For simplicity, in the paper, integral SMC technique [25] is chosen to design control signal of DTC-IM drive for robustness to high uncertainty of stator resistance. In order to ensure boundary condition of system's Lyapunov stability and reduce chattering-phenomenon, a load estimation method based on dynamic equation of rotational motion and Kalman lter [6] is utilized. In next section, SMC drive structures for DTC drive are presented.…”

The paper presents an application of sliding mode controller and Kalman Filter (KFSMC) in speed control of pulse-width-modulation direct torque controlled induction motor drive. The performance of the direct torque control (DTC) is degraded by the uncertainty of stator resistance. In order to increase the robustness of the controlled system to the uncertainty, a sliding mode controller (SMC) is utilized to replace the proportional-integral (PI) speed controller in the conventional DTC drive structure. Computation of SMC requires estimation of load, and Kalman Filter is integrated to reduce noise in load estimation and chattering phenomenon in speed response. Simulations are carried out at different reference speeds in a wide range of noises of stator resistance. Indices including ITAE, settling time, overshoot, and undershoot are employed to compare the performance of drive structures. Results confirmed the desired characteristics of the proposed drive structure.This is an Open Access article distributed under the terms of the Creative Commons Attribution License (http://creativecommons.org/licenses/by/4.0/), which permits unrestricted use, distribution, and reproduction in any medium provided the original work is properly cited.

The paper deals with the utilization of Kalman filter and fuzzy logic control in induction motor drive with direct torque control (DTC). In order to lower ripple of stator current vector in DTC drive, pulse width modulation technique with high switching frequency is applied. However, the performance of the DTC also depends on the accuracy of both stator resistance and stator current vector. In the paper, the stator resistance and stator current components are assumed to be distorted by Gaussian noises. In order to reduce the effect of noises especially at low speed and very low speed regions, a simple Kalman filter is applied for filtering current components, and fuzzy logic theory is used to increase the flexibility of proportional-integral (PI) compensator in the speed controller of the drive structure. Simulations are implemented in conditions of high-level noises of stator current and stator resistance, and a wide range of load torque. An ITAE-based criterion is utilized to evaluate the performance of drive structures. Results confirmed the expected dynamic properties of the proposed drive structure.
