Off-highway dump truck contains amounts of potential energy and kinetic energy. During the braking process, these two parts are consumed in the form of heat on the braking resistance, and the energy consumption will be about 24 percent of total energy consumption of the Truck. Hence, it is necessary to recover the braking energy. This paper, aiming at the characteristics of electric drive system in...
It is difficult to obtain a more precise mathematical model of parallel-inverter system with a nonlinear load. Nonlinear load is the general factor which affects output voltage total harmonic distortion (THD) and current sharing. But fuzzy controller can control well without a precise mathematical model. Master-slave control is used to control the parallel-inverter system in this paper. The voltage...
Performance of DC/AC Inverters is decreased due to variable load parameters. Based on a voltage and current double closed-loop control inverter model, a novel load on-line parameter estimation control method is proposed. In this method, load parameters of inverters are calculated on-line. And then, controller coefficients of inverters are modified according to load parameters. Modify strategy of controller...
Soft starters are being used as induction motor starters in fan or pump drives, etc, the principle of which is based on the control of variable voltage and constant frequency. In the paper, we develop a kind of intelligent soft-starter for AC motors based on TMS320F240 digital signal processor (DSP). The method of designing the system that includes hardware and software is introduced. A new method...
