This paper presents a novel torque control method for two-level-inverter-fed induction motor drives. The control principle is based on a finite-control set model predictive control (FCS-MPC) using a state tracking cost index. In the online procedure of the proposed FCS-MPC, the optimal voltage vector and its corresponding optimal modulation factor are determined based on the principle of torque and...
In this paper, two schemes of a model predictive control (MPC), namely finite control set with modulation control (FCS-MPC) and dead-beat model predictive control (DB-MPC) as a continuous control set (CCS-MPC) are applied to permanent magnet synchronous motor (PMSM) for torque control. The FCS-MPC strategy chooses the optimal output voltage vector with its optimal modulation interval. In CCS-MPC strategy,...
This paper presents an experimental evaluation of performance of a complete electric vehicle (EV) system. Experimental implementation of powertrain is presented and then the performance of each plant is tested and assessed. This drivetrain includes two permanent magnet synchronous motors (PMSMs), two power converters with their gate drivers, the control board of TMS320F28335 DSP, and energy storage...
fast speed-tracking with limits commitment for currents and voltages of drivetrain is crucial for EV/HEV. This study proposes a fast-speed drive for permanent magnet synchronous motor (PMSM) based on Model Predictive Control (MPC). Fast speed tracking is achieved through optimization of the DC source utilization. With common torque and current limits, the proposed technique predicts the optimum voltage...
In this paper, a new integrated control system via visual-servoing and cascaded proportional derivative (PD) controllers for an autonomous hexacopter is proposed. The spherical image based visual servoing is designed to control the hexacopter to the desired pose with respect to an arbitrary target in three-dimensional (3D) workspace based on images captured. Meanwhile, the cascade-PD controller is...
Characteristics of a small scale wind turbine using Permanent Magnet Synchronous Generator and connected to a grid through a reduced switches count converter (two legs only) are studied in this paper. Active power output corresponding with the input is given with the reactive power produced by the wind turbine regulated at 0 MVAr. Variable wind speed is optimum for drive train performance at 10 m/s...
