This paper presents a new and simple finite-control set model predictive control strategy to reduce the torque ripple in permanent-magnet synchronous machines (PMSMs). The method is based on minimizing a cost function that considers the flux linkage torque harmonics obtained from a discrete-time model of the machine. The power converter switching state that minimizes this cost function is selected...
This research article deals with the two closed loop speed control techniques namely Vector Control and Direct Torque Control for Permanent Magnet Synchronous Motor Drive. These two control techniques are critically evaluated for the performance comparison in terms of starting response, steady state response and transient condition. The simulation models of the two controllers are developed in Matlab/Simulink...
Multiphase electric drives have been recently proposed for applications where the highest overall system reliability, combined with a reduction in the total power per phase, are required. Strategies like Field Oriented Control (FOC) and Direct Torque Control (DTC) have been traditionally used in these high performance applications. In this paper, a Predictive Torque Control (PTC) method is introduced...
This paper presents a new control strategy for three-phase induction motor which includes independent speed & torque control loops and the current regulation thereby overcoming the limitation (i.e. sluggish response) of volts per hertz controlled industrial drives. For close-loop control, the feedback signals including the rotor speed, flux and torque are not measured directly but are estimated...
The strongly nonlinear magnetic characteristic of switched reluctance motors (SRMs) makes their torque control a challenging task. In contrast to standard current-based control schemes, we use model predictive control (MPC) and directly manipulate the switches of the dc-link power converter. At each sampling time a constrained finite-time optimal control problem based on a discrete-time nonlinear...
Direct torque control (DTC) can directly control the inverter states in order to reduce the torque error within the prefixed band limit. DTC of brushless dc drive with trapezoidal back-EMF is presented in this paper. Using the rotor flux vector position in alpha-beta axis stationary reference frame and torque error, the proper switching pattern can be selected to control the generated torque and reducing...
