This paper presents a new control strategy of autonomous mobile robot in running environment. The robot is considered as an individual agent aimed at executes different tasks in term of motion under constraints applied on robot structure. The flat model of Pioneer 3dx robot is developed in order to prove that the system is flat and has various helpful properties which can be exploited to build the...
In this paper, simulation and practical implementation of direct power control is presented for a PWM Rectifier application. The proposed DPC control has several advantages, including the grid current very close to sinusoidal waveforms (TDH < 1.2%), and good regulation of DC-bus voltage is achieved using the PI controller. The simulation and the experimental results obtained in this study, demonstrate...
This paper describes the control by the selective harmonics elimination PWM of three level inverter using FPGA device. The NPC inverter is realized with six similar modules type Mitsubishi. Each one contains two bi-directional IGBTs. To control the four semi-conductors of each leg, switching angles allowing the elimination of the 5th, 7th and the 11th harmonic have been computed basis on the SHEPWM...
