“…The correct values of the coefficients are selected using the linearised and averaged torque control loop. With the purpose of the correct definition of the coefficients K p and K i as mentioned in [44], the following conditions must be satisfied for the positive and negative torque slopes obtained from (59) and (60), respectively:

\begin{matrix} alignleft \\ right ⟨p o s i t i v e s l o p e⟩ & left \geq - A_{t} t_{e} + B_{t} |{\vec{v}}_{s}| + {K_{p}}^{+} (\frac{ω_{s}}{d} - ω_{r}) \end{matrix}

\begin{matrix} alignleft \\ right false⟨ n e g a t i v e s l o p e false⟩ & left \geq - A_{t} t_{e} - K_{p}^{-} ω_{r}) \end{matrix}

“…In this case, estimation and control performances of the observers and the drive systems are reduced. The realization of the control and estimation algorithms with low T is very limited with DSP-based processors which have sequential processing capability [44,45]. Therefore, FPGAs which are proposed as an alternative to DSP-based processors with their parallel processing capability and fast system response, are preferred in applications where the control and estimator algorithms should be performed with low T. In the FPGA-based industrial applications, system generator toolboxes like hardware description language (HDL) coder and Xilinx System Generator which are embedded in Matlab Simulink and require to pay registration charge for licence key are usually used to generate automatically the HDL commands for FPGA hardware synthesis [46].…”

This study proposes an FPGA‐based hardware in the loop (HIL) emulator for speed‐sensorless of induction motor (IM) constant switching frequency controller‐based direct torque control (CSFC‐DTC) with a novel bi input‐reduced order extended Kalman filter (BI‐ROEKF). The full precision single floating point numbers in the IEEE 754 standard are used during the implementation of the HIL emulator which contains closed‐loop speed‐sensorless drive system of IM on the Xilinx Virtex XC5VLX‐110T ML506 FPGA board. In this HIL emulator of speed‐sensorless IM drive system, stator stationary axis components of stator flux, rotor mechanical angular speed, load torque, stator and rotor resistances are estimated with the novel BI‐ROEKF which is proposed for the first time in the literature. The proposed BI‐ROEKF is created by applying two different non‐linear and linear system input functions obtained from two different IM models to the single reduced order extended Kalman filter (ROEKF) algorithm. Thus, the order and the computational burden of the EKF are reduced. The HIL emulator of the speed‐sensorless drive system of IM is implemented on FPGA using the advantage of hand‐written VHDL on getting an optimal logical design to reduce the sampling time which directly effects the estimation performance of the model‐based estimator like the novel BI‐ROEKF and hence the control performance of drive system. The estimation performance of the novel BI‐ROEKF is tested with speed‐sensorless CSFC‐DTC IM drive system under different challenging scenarios in HIL emulator. Thus, the control and the implementation performances of digitalised emulator are tested. Finally, the estimation and control performance results and the execution time of the each part of the proposed HIL emulator of the speed‐sensorless BI‐ROEKF‐based CSFC‐DTC of the IM are presented.

“…Nowadays, FPGA technology has been recognized as a promising candidate and widely adopted for the controller platform in embedded control systems [3,4,5], including high performance AC motor drives [6,7,8]. For multi-motor control systems, the demand of numerous resources and embedded multipliers for control algorithms often limits the number of controlled motors within a single chip.…”

Often, the demand for optimal and harmonious operation of multi-motor control systems requires sharing of feedback information from one drive to other drives. From the point of view of controller implementation, a multi-controller structure degrades the system integration and requires data communication among chips. The aim of this paper is to propose a fully integrated single chip solution for a cross-coupling multi-motor control system. The proposed speed controller with time-division multiplexing scheme can simplify the entire system, making possible the implementation on a single device. The experimental results confirm the implementation feasibility and the effectiveness of the proposed single chip system.
