This paper presents a new three-phase five-level inverter for direct torque control (DTC) drives application. The advantages of the inverter are reduced output harmonics, switching losses and number of power switches. The multilevel PWM modulation method as well as output voltage analysis based on symmetrical sampling are presented. The proposed inverter is compared with the conventional invert...

Permanent Magnet Synchronous Machine (PMSMs) are considered as the promising electromagnetic structure, especially for In-Wheel motor electric and hybrid propulsion applications. The design for a direct-drive wheel motor PMSM require a 3D Finite Element Analysis (FEA) based investigation of the output torque especially when the end winding is considered and in the case of skewed machine, this p...

Permanent magnet synchronous motor (PMSM) AC servo system has the characteristics of uncertainty, time-varying, nonlinear and fractional order. Applying traditional control method is difficult to achieve desired effect. The fuzzy strong adaptability parameter change, nonlinearity imprecise model controlled object. simulation permanent three closed-loop systems established. principle realization...

In this paper, a novel method based on a combination of Extended Kalman Filter (EKF) with Self-adaptive Differential Evolution (SaDE) algorithm to estimate rotor position, speed and machine states for a Permanent Magnet Synchronous Motor (PMSM) is proposed. In the proposed method, as a first step SaDE algorithm is used to tune the noise covariance matrices of state noise and measurement noise i...

Permanent Magnet Synchronous Motor (PMSM) is a non-linear, complex time-varying system. The control performance is not satisfactory in the traditional PID control method. Based on the combination of PI and fuzzy control, the controller of fuzzy self-adaptive PI was designed in this paper. The PID parameters can be set with fuzzy algorithmic approach automatically. Experimental results show that...

In this paper, an adaptive fuzzy backstepping controller has been developed for the position tracking control of a permanent magnet synchronous motor (PMSM) drive. Fuzzy logic systems are used to approximate unknown nonlinearities appearing in the control law and an adaptive backstepping technique is employed to construct controller. To illustrate the performance of the proposed controller comp...

In this paper, the basic principle of permanent magnet synchronous motor direct torque control, and response performance control are investigated. PMSM model is built simulated on MATLAB / SIMULINK platform. The simulation results show that system have fast response, good dynamic can quickly follow a variety changes given torque. But in full range run-time, has relatively large ripple rich harm...

A New Adaptive Self-Tuning Fourier Coefficients Algorithm for Periodic Torque Ripple Minimization in Permanent Magnet Synchronous Motors (PMSM) Torque ripple occurs in Permanent Magnet Synchronous Motors (PMSMs) due to the non-sinusoidal flux density distribution around the air-gap and variable magnetic reluctance of the air-gap due to the stator slots distribution. These torque ripples change ...

As an important component of vehicle design and energy conservation, electric dynamics simulation is essential, especially under complicated testing conditions. The current commercial software mostly used for fuel simulation, which lacks accurate powertrain parts open sources. To address this problem, paper proposes open-source flexible platform that includes 27 degrees freedom (DOFs) based on ...
