The adaptive inverse control is a novel method in control system. It makes set signal, parameter disturbance and external disturbance separately controlled and makes them reach the optimal control without compromiseThe traditional adaptive inverse control system often used FIR filters. It madde the system costing long training time and slow convergence. So, it is unable to adapt the requirement...

This paper proposes a new scheme of reconstructing current sensor faults and estimating unknown load disturbance for a permanent magnet synchronous motor (PMSM)-driven system. First, the original PMSM system is transformed into two subsystems; the first subsystem has unknown system load disturbances, which are unrelated to sensor faults, and the second subsystem has sensor faults, but is free f...

The paper deals with real-time control of PM synchronous motor for sensorless position using Power PC-MPC processor. Real parametric-and real-time model could be ideal tools for both control and simulation of the PMSM (permanent magnet synchronous motor) position drive. Unfortunately that idealized model doesn’t exist so far. Such a model has to face following serious problems: it must be excit...

In this paper, an improved online particle swarm optimization (PSO) is proposed to optimize the traditional search controller for improving operating efficiency of permanent magnet synchronous motor (PMSM). This algorithm combines advantages attraction and repulsion PSO distributed that can help find optimal d - axis air gap current quickly accurately under non-stationary conditions, thereby mi...

In this paper a Sliding Mode Control scheme (SMC) applied to the Permanent Magnet Synchronous Motor (PMSM) speed control is designed and improved. A Fuzzy logic algorithm is added to mitigate chattering caused by discontinuous term in steady states, and to ensure good performances of the controller in transient states. The proposed Fuzzy-SMC performance is tested in simulation and experimental ...

Presented in this article is a method for decoupling the speed and flux control of three-phase permanent magnet synchronous motor (PMSM) during an open-circuit fault (OCF) using current controller based on proportional resonant (PR) techniques. The suggested approach relatively simple to implement maintains good operation open circuit. PMSM performance under pre-fault, OCF, post-fault condition...

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. It found that DTP PMSM, wide speed range possible not only torque-producing sub...

High-efficiency motors are being gradually introduced in many industrial applications because of their positive impacts on the environment by reducing energy consumption and CO2 emission. In this respect, line start permanent magnet synchronous motors (LS-PMSMs) have been introduced recently. Due to their unique configuration, LS-PMSMs allow the obtaining of super premium efficiency levels, acc...

The permanent magnet synchronous motor (PMSM) is a highly efficient energy saving machine. Due to its simple structural characteristics, good heat radiation capability, and high efficiency, PMSMs are gradually replacing AC induction motors in many industrial applications. PMSM has nonlinear system lies on parameters that differ over time with complex high-class dynamics. To achieve the excessiv...

Due to the frequently changing working conditions and complex operating environment of electric vehicle permanent magnet synchronous motor(PMSM), motor parameters change dramatically. However, performance PI current regulator, which is most widely used, sensitive has weak robustness, will lead deterioration control system performance. To address this problem, active disturbance rejection (ADRC)...
