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...
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...
