The dead zone and voltage drop of inverter power switches make the currents in asynchronous motor drive system contain a large amount of harmonic. This aberration of currents waveform influences the efficiency of motor drive system. Aim at this problem, this paper proposes a harmonic injection method to eliminate the currents harmonic component when the motor is running, which improves currents waveform of motor and boosts efficiency of motor drive system. The effectiveness and real-time performance of this algorithm is verified via the simulation and the contrast experiment. Through the result of simulation, five times harmonic content decreased from 9% to 2%, the total harmonic distortion of voltage (THD) decreased from 6% to 2%, and efficiencyis increased from 98.99% to 99.95%.

This paper presents the comparison of performance between matrix converter and conventional DC-link converter fed induction motor drive system. It is noted that conventional converter required two stages for power conversion whereas matrix converter required single stage. The output current from conventional converter contains odd harmonic component which produces additional losses in drive causes de-rating and torque pulsation of motor. This unhealthy operation of drive is reduced by matrix converter which has the unique feature of producing pure sinusoidal output current waveform with minimum harmonic distortion. The main objective of this paper is to reduce total harmonic distortion by employing proper switching of matrix converter. The simulated result is compared with conventional converter to show that proposed system is better than conventional system. This paper also presents modeling and simulation of matrix and conventional converter fed induction motor drive system using MATLAB/SIMULINK software.

In this paper, finite-set model-predictive control (FS-MPC) is inducted for a motor drive system. The dynamic response and multiple constraint handling nature of FS-MPC are the major factors that stand out among the controller family. However, for real-time implementation, the computational burden of FS-MPC is a primary concern. Due to the parallel processing nature and discrete nature of the hardware platform, the field-programmable gate array (FPGA) can be an alternative solution for the real-time implementation of the controller algorithm. The FPGA is capable of handling the computational requirements for FS-MPC implementation; however, the system development involves multiple steps that lead to a time-consuming debugging process. Moreover, specific hardware coding skill makes it more complex, corresponding to an increase in system complexity, which leads to a tedious task for the system development. This paper presents a FPGA-based implementation of the predictive current control of a permanent magnet synchronous motor (PMSM). FS-MPC of the PMSM drive system is designed and implemented using the digital model integration approach provided by the Xilinx system generator (XSG) and VIVADO platform. The step change in the load disturbance as well as the reference speed is considered for the analysis of the controller for the motor drive system. Moreover, the steady state error and harmonic distortion in the motor current is considered for an in-depth analysis of the system performance corresponding to different sampling frequencies.

Background: A multi-motor synchronous drive control system is widely used in many fields, such as electric vehicle drive, paper making, and printing. Methods: On the basis of the optimized structure of ADRC, a fuzzy first-order active disturbance rejection controller was developed. Double channels compensation of extended state observer was employed to estimate and compensate the total disturbances, and an approximate linearization and deterministic system was obtained. As the parameters of ADRC are adjusted online by a fuzzy controller, the performance of the controller is effectively improved. Results: Based on the SIMATIC S7-300 induction motor control experimental platform, the performances of anti-interference and tracking performance are tested. Conclusion: The actual experimental results indicated that compared with PID control, induction motor drive system controlled by fuzzy ADRC has higher dynamic and static status and following performances and stronger anti-interference abilities.
