This paper investigates the design of a robust linear parameter-varying (LPV) controller for speed regulation surface permanent magnet synchronous motors (SPMSMs). Motor dynamics is defined in t...

Nonlinear systems are difficult to control and may exhibit chaotic behavior under certain parameters selection. Typical example of these systems is the well known Lorenz attractor. In this paper passive theory is used to design controllers to a class of minimum phase nonlinear systems. The feedback controllers guarantee asymptotic stability of the closed loop system. The method is applied to a ...

Abstract This paper introduces the structure and characteristic of two novel kinds of hybrid excitation linear synchronous motor with permanent magnet and electric excitation-alternant hybrid excitation and even hybrid excitation linear synchronous motor. The air-gap magnetic field of them is analyzed with ANSYS8.1 software package. The results of the distribution of magnetic field and the elec...

The gamma-band synchronous oscillatory activity (40}60 Hz) appears in various sensory and motor cortical areas. Because both sensory stimuli and motor responses are characterized by many analog variables, questions are raised regarding whether cortical neurons manage to transmit analog information within the gamma-oscillatory activity. Here, based on the sampling theory in digital signal proces...

Abstract— Power system engineers and design engineers use normalized values for the variables. This paper presents dynamic modeling and simulation of 3-phase induction motor using dq0 axis transformation of normalized stator and rotor variables in the synchronous reference frame assisted by MATLAB/SIMULINK. For this purpose, the relevant electrical differential equations and mechanical differen...

This paper presents a comparative study on two most popular control strategies for Permanent Magnet Synchronous Motor (PMSM) drives: field-oriented control (FOC) and direct torque control (DTC). The comparison is based on various criteria including basic control characteristics, dynamic performance, and implementation complexity. The study is done by simulation using the Simulink Power System B...

In coping with the trend toward the much higher powered electric-motor driven injection molding machine, multi-AC servomotors control system has become necessary in order to control the molding machine mechanism. Thus, it is inevitable to use a synchronous positioning control technique not to cause the excessive mechanical stress in the machine body. It is possible to realize the synchronous po...

Based on the equation of small pure electric vehicle (PEV) and the mathematic model of permanent magnet synchronous motor (PMSM), synchronous motor (PMSM), the dynamic model is presented for small PEV driven by PMSM. With space vector pulse width modulation (SVPWM) algorithm, a velocity and current double closed-loop simulation model of PMSM control system is build in Matlab7.6/Simulink environ...

Multi-motor synchronous system is a multi-input multi-output, nonlinear and high coupling control system. The neural network generalized inverse system can realize the linearization and decoupling of the nonlinear control. Local minima, irrationality learning rate and over learning easily occur in traditional feedforward neural networks. To overcome the problems, it put forward a single hidden-...
