Field‐oriented control based on hysteresis band current controller for a permanent magnet synchronous motor driven by a direct matrix converter

Abstract

The hysteresis band controller offers excellent dynamic performance. It has been widely researched and applied for the voltage source inverter and inverter fed drives, however it has not been investigated within the context of a matrix converter or a matrix converter based motor drive. In this paper, both fixed-band and sinusoidal-band hysteresis current controllers are proposed and developed for a direct matrix converter. A comprehensive comparative evaluation of the two methods is then carried out. Both methods have fast dynamic performance and they inherently integrate the line modulation technique of the virtual rectifier stage into the overall modulation. Surge currents are prevented with the proposed scheme. The sinusoidal-band hysteresis controller demonstrates lower total harmonic distortion at the expense of higher average switching frequency, which is only significantly observable at very high sampling frequencies. The proposed controller is integrated with the field-oriented control to drive a matrix converter fed permanent magnet synchronous machine. The proposed methods are simple and incur a light computational burden, which advances the practical applications of matrix converters in AC motor drives. The simulation and experiment results demonstrate the effectiveness and feasibility of the proposed scheme.

Performing reactive power compensation of three-phase induction motor by using parallel active power filter

“…Various current control methods have been applied to generate switching signals in active power filters [29]. In this paper, in order to obtain switching signals, HBCC was used as a control method.…”

Comparative Analysis of Current Control Techniques to Support Virtual Inertia Applications

“…Alternate techniques to keep the switching frequency constant are proposed in [30,31]. In [32], a method of using a sinusoidally-varying hysteresis band is proposed to reduce the output current and power ripple. However, for simplicity, a generic hysteresis current controller as shown in Figure 4 is discussed in this paper.…”

Sequential Model Predictive Control of Three-Phase Direct Matrix Converter

“…In academia, many control techniques have been researched for MCs [5,6]. These mainly include the Venturini method [7,8], space vector modulation [9,10], direct torque control [11,12], hysteresis control [13,14], and model predictive control (MPC) [15][16][17][18]. The performance comparison of these control techniques is summarized in Table 2.…”
