This paper presents a new position control method for transverse flux machines. Since the torque ripple is one of the most important reasons for the low dispersal of transverse flux machines, a great importance has to be attached to subordinate torque control. Based on a look-up table, the torque is controlled by a time-discrete converter state changing. Speed and position are superordinately controlled...
A novel flywheel reaction torque measurement system is proposed to measure the output torque of flywheels. The system structure and principle of the measurement system are presented. Finite-element method is applied to compute the magnetic field and characteristics of the measurement system. An improved disturbance observer is applied in the position closed loop control system. Simulation and experiment...
This paper presents a novel control scheme for a two-phase synchronous reluctance motor (TPSynRM) . A three-leg two-phase inverter is used to drive the TPSynRM. The torque of the TPSynRM is controlled with a direct torque control (DTC) method. DTC uses the space vectors of the three-leg inverter. The speed controller has a two-degree of freedom (TDOF) structure. A pole-zero cancellation (PZC) method...
Brushless DC (BLDC) Drives find immense applications in various control systems, especially in position control. Such applications require fast dynamic response with excellent stability and steady state performance. In order to meet this requirement, brushless dc drives should respond with improved performance. In this paper, a typical brushless dc motor drive system used for control applications...
A robust position controller with variable structure control (VSC) and dynamic recurrent fuzzy wavelet network (DRFWN) technique for permanent magnet synchronous motor (PMSM) is presented in this paper. Based on the VSC method, the closed-loop system can system dynamics with an invariance property to uncertainties. However, the sliding controller based the assumption of known uncertainty bounds often...
