Resonant wireless power transmission has the advantages of long transmission distance and high efficiency. Series — series (SS) transmitting and receiving system is suitable for small load research. In this paper SS-type circuit is analyzed and discussed by using equivalent circuit theory. The mathematical models of the transmission efficiency and output power are derived. The influencing factors,...
As the main power source of the industrial system, the control accuracy of a motor directly affects the efficient operation of the system. In this paper, an adaptive control strategy based on disturbance observer is proposed for a Permanent Magnet Synchronous Motor (PMSM) with multiple disturbances. Firstly, the multiple disturbances in a PMSM are divided into the modeled load and the norm bounded...
In the actual permanent magnet synchronous motor servo system, the load changes is a major factor that affects system performance. In this paper, a PMSM vector control system model is estabLished in Matlab/SimuLink environment. By adjusting the parameters of controller, simulation and analysis are done on the load changes that may appear. The results demonstrate that the system is stable, with good...
This paper mainly focused on the theoretical studies of the linear rudder electric servo loading system. The mathematical model of motor servo loading system is established. Then, the disturbance force which would influence the system's dynamic performance is analyzed. In order to improve the accuracy of loading system, a feedforward-PID control algorithm is proposed. The algorithm can improve the...
The current regulation based on the internal model control is applied to vector control of PMSM. It avoids the adjustment of two PI-parameters; moreover the IMC structure improves the characteristic of the current loop. Generally, the flux of PMSM is changing with the load current (torque). Simulation results under flux saturation considered and not considered show that the current internal model...
In this paper, the linear and nonlinear models are put forward first to describe load balancing system for parallel cluster computing. Through analyzing the stability of linear model, this paper finds the asymptotic stable condition of load balancing system with some assumptions, and the simulation results are given to compare the results in theory later. Based on the analyzing and simulation results,...
