Calculation and simulation of transient optimal voltage output point in wireless sensor networks

Abstract

For production of transient voltage output in wireless sensor network, due to the instability of the control voltage, the traditional control method needs to introduce the feedback control, through the establishment of mathematical model for periodic monitoring of the output voltage, change control strategy once the problem is found, lead to slow control time computation, cannot obtain the optimal output voltage values. A new method for calculating transient optimal voltage output points in sensor network of two-phase rotating and stationary coordinates is proposed. Through the analysis of the mathematical model of the network transient, the repetitive controller is designed on the two axes. By calculating the mean value of maximum and minimum value of the voltage, the transient energy-saving voltage output of the sensor network is monitored in real time. The control process of output voltage quality of sensor network with nonlinear load is analyzed, and the feed forward control method of parameter on line control is put forward. Under the premise to meet the control accuracy, enhance the response speed and stability of voltage output control of sensor networks. Simulation results showed that the method presented in this paper improves the poor effect of traditional methods, solves the complex problems of network energy-saving voltage control, and control effect of energy-saving voltage output is great, and the optimal voltage output values is obtained.
