In this paper an effort is made to represent the behaviour of a ship propulsion system comprising a Permanent Magnet Synchronous Motor (PMSM) driven by a 6-pulse driving system using the Direct Torque Control (DTC) control technique. The DTC technique cited is emulated via MATLAB's Simulink toolbox while all study cases are performed successfully in MATLAB's Power System Blockset environment.
An adaptive fuzzy control method is developed to control chaos in the permanent magnet synchronous motor drive system via backstepping. Fuzzy logic systems are used to approximate unknown nonlinearities, and an adaptive backstepping technique is employed to construct controllers. The proposed controller can suppress the chaos of PMSM and track the reference signal successfully. The simulation r...
31 www.erpublication.org Abstract—In order to overcome the nonlinear characteristics of permanent magnet synchronous motor (PMSM), fractional order (FO) fuzzy proportional integral (PI) controller was designed based on the fractional order calculus and fuzzy technology for PMSM with the nonlinearity and time-varying parameters at work. Fuzzy control rules are designed in the light of running ...
The paper describes an investigation of fault tolerant control strategies for permanent magnet synchronous motor (PMSM) driven by a fault-tolerant inverter. The inverter is a topology-modified inverter with fault-tolerant capability, which can be configured as the standard 3-phase 6-switch inverter and reconfigured as 3-phase 4-switch or 2-phase 4switch inverter under the fault condition. By an...
In this paper, the application of sliding-mode control to a permanent-magnet synchronous motor (PMSM) is presented. The control design is based on a generic mathematical model of the motor. Some dynamics of the motor and of the power amplification stage remain unmodelled. This model uncertainty is estimated in realtime. The estimation is based on the differentiation of measured signals using th...
This paper studies the use of the PMSM (permanent magnet synchronous machine) generators instead of the induction based alternating current generators in renewable energy sources (wind turbines, combined heat and power, etc.). The paper considers the most significant advantages of the novel permanent magnet technology such as increased specific power, high torque, reduced maintenance costs, inc...
Permanent Magnet Synchronous motor (PMSM) has received widespread acceptance in recent years. In this paper, a new rotor and stator Magnetic Fields Direct-Orthogonalized Vector Control (MFDOVC) scheme is proposed for PMSM servo system. This method simplified the complex calculation of traditional vector control, a part of the system resource is economized. At the same time, through the simulati...
A robust two-degree-of-freedom control scheme is proposed for permanent magnet synchronous motor PMSM using extended state observer ESO . The robustness is achieved based on the ESO. Parameter perturbation and external disturbances in PMSM drive system are treated as disturbance variable, and then the motion model of PMSM is transformed into an extended state model by introducing this disturban...
A permanent magnet synchronous motor (PMSM) with sinusoidal flux distribution is commonly coininutated using discrete rotor position feedback from Hall sensors. A commonly used stator current excitation strategy used in such a system is a six-step current waveform. Application of sinusoidal current waveforms is shown to produce smooth torque in the PMSM. This paper shows how a pseudo-sensorless...
On the basis of analysis of dq model of permanent magnet synchronous motor (PMSM) and principle of field oriented control (FOC), detail modelling of PMSM drive system and simulation results presented in this paper. The PMSM model is based on electronic components rather than mathematical blocks, this enabled us to achieve simulation results more realistic. Moreover all the modules of this simul...
