直流侧超级电容器储能的能量回馈控制的研究

Super-capacitor has such characteristics as high-power density, small internal resistance and be suitable for high current charge and discharge rapid. Motor for high-speed launching should have a good driving and braking performance; to recover the braking energy is important for improving the efficiency. At the background of linear launching, based on the model of permanent magnet synchronous motor, this paper presents the PMSM vector control algorithm and concretely analyses the working mechanism and high speed power braking regeneration process of the control system, the super-capacitor can quickly absorb the braking energy in the DC side. At last, combined with the control strategy of the launching system, the simulation about the energy regeneration is made in MATLAB software, the simulation results show that the system has good performance.
