The dual motor drives fed by a single inverter are purposely designed to reduce size and cost with respect to single motor drives fed by a single inverter. This paper presents the speed responses behavior of Dual Permanent Magnet Synchronous Motor (PMSM) driven by Mean and Differential Torque Control technique. The drive is simulated by using Hysteresis Current Controller. MATLAB/Simulink is ch...

Two rotor position estimation methods for a dual three-phase (DTP) permanent magnet synchronous machine (PMSM) are investigated in this article, where the is estimated by exploiting saliency of motor through phase current derivative measurement during fundamental PWM excitation standard six-phase two-level inverter.

Abstract: High-efficiency permanent-magnet synchronous machine (PMSM) drive systems need not only optimally designed motors but also efficiency-oriented control strategies. However, the existing control strategies only focus on partial loss optimization. This paper proposes a novel analytic loss model of PMSM in either sine-wave pulse-width modulation (SPWM) or space vector pulse width modulati...

In this paper, using a personal computer (PC), the practical implementation of scalar and vector control methods on a three–phase rotor surface- type permanent magnet synchronous machine drive is discussed. Based on the machine dynamic equations and the above control strategies, two block diagrams are presented first for closed-loop speed controlling of the machine drive/system. Then, the desig...

This paper focuses on the performance improvements of the permanent magnet synchronous motor (PMSM) using vector control. In this paper, a neural adaptive sliding mode control algorithm is proposed to accomplish the position tracking of the field-oriented control (FOC) for PMSM. The proposed algorithm is presented by combining the fast terminal sliding mode (FTSM) with the radial but also solve...

In recent years, permanent magnet synchronous motors (PMSM) have gained variety industrial applications, because of simple structures, high efficiency and ease of maintenance. But these motors have a nonlinear mathematical model. To resolve this problem several studies have suggested the application of vector control (VC) and direct torque control (DTC) with soft-computing (SC) technique. This ...

The problem of speed control of a permanent magnet synchronous motor (PMSM) with unknown parameters and unknown external load torque is formulated and solved as an adaptive control problem that meets the requirements of asymptotic command following with simultaneous asymptotic disturbance attenuation. The key point is to identify the system without knowledge, estimation or measurement of the un...

Based on Takagi–Sugeno (T–S) fuzzy approach we design a fuzzy speed control system for a permanent magnet synchronous motor (PMSM). We derive sufficient conditions for the existence of a T–S fuzzy speed regulator and acceleration observer in terms of linear matrix inequalities (LMIs). We parameterize the gain matrices using the LMI conditions. We implement the proposed T–S fuzzy speed control s...

This paper presents the methodology of tuning two position servo drive systems with Permanent Magnet Synchronous Motors (PMSM): Field Oriented Control (FOC) based on current model of motor and FOC based on voltage model of motor. These two strategies are Vector Control (VC) methods and provide a solution for high performance drives but the choice one of these algorithms determines the type of i...
