Reducing number of static converters in electromechanical systems will lead to a global degradation of energy efficiency. In the case of Mono-Inverter Dual-Permanent Magnet Synchronous Machine (MIDPMSM) system, several studies have shown this effect especially when the load torques are different. In this paper, after analyzing the performance of Optimal Predictive Control (OPC) for MIDPMSM system...
This section presents a structure of a control topology of a PMSM, whose objective is to eliminate the mechanical sensor and ensure continuity of service even fault presence opening a phase. A MRAS observer is used to replace the mechanical sensor and a redundant inverter leg is used to replace the faulty leg.
Permanent Magnet Synchronous Motor (PMSM) with lower inductance values suffering from the narrow Constant Power Speed Range (CPSR). The traditional approaches for extending CPSR operation included adding an additional inductance or a thyristor controlled inductance in series with the motor. However, these approaches increase the cost, complexity, and derate the inverter of the drive system. In this...
This paper proposes Comparative Study between PI and sliding mode controllers in fault tolerant PMSM drive. The proposed drive is a three phase PMSM connected to four leg inverter when the fourth leg is always closed to the neutral point of the machine. The fault tolerance is reached by using a PI and Sliding mode controllers and a modified space vector modulation applied at post fault mode. The PI...
PMSM has been used widely in elevator speed control system. Based on the mathematical model of PMSM and algorithm of inverter (CFPWM, SPWM, SVPWM), PMSM vector control systems are built. By the software of MATLAB/Simulink, the control systems using three inverter methods of CFPWM, SPWM, SVPWM are comparative simulated and analyzed. The results show that the oscillating of torque, speed, and magnetic...
An adaptive flux weakening control scheme is proposed for the surface permanent magnet synchronous machine (PMSM). The method adaptively controls the demagnetizing current with changes in speed or load torque. The method does not require DC bus voltage sensing of the power converter and unsusceptible to the motor parameter changes. No requirement of bus voltage makes it suitable for voltage sensor...
In this paper, we present the linearizing control technique controlled by a neuro-fuzzy regulator applied to the permanent magnet synchronous machine (PMSM). It permits decoupling and linearizing the system without taking into accounts the flux orientation. The nonlinear control (NLC) applied to the PMSM decompose the system into two mono variable, linear and independent subsystems. The neuro-fuzzy...
This paper describes a fast torque control system of permanent magnet synchronous motor (PMSM) based on model predictive control (MPC). This torque controller selects directly one of the voltage vector of voltage source PWM inverter considering voltage saturation explicitly. To obtain the fast torque response at the transient state and the stable current response at the steady state, the problem with...
Control of an advanced high-speed flywheel energy storage system (FESS) based on a high-speed surface mount permanent magnet synchronous machine (PMSM) is explored in this paper. A PWM inverter/rectifier controls the bi-directional flow of energy for charging and discharging the flywheel. During charging, an inner current loop controller and an outer speed loop controller regulate the system performance...
This paper presents the development of high fidelity real-time model of a permanent magnet synchronous motor (PMSM) drive, to be used in hardware-in-the-loop (HIL) application. The PMSM model is based on a finite-element analysis (FEA) method and implemented on an FPGA chip. The motor inductances and flux maps are computed from the JMAG-RT finite element analysis software. A 3-phase IGBT inverter...
