摘要
太阳能两轮电动车所处环境的多变性导致了太阳能电池板的输出不稳定。为了保证电机负载稳定工作,进行了太阳能两轮电动车能量控制的研究。基于滑模变结构控制原理设计了追踪太阳能电池最大功率输出点的控制策略,同时设计了新型DC/DC变换装置,实现了太阳能电池与蓄电池的联合供电。搭建MATLAB仿真平台,通过改变直流母线端负载来测试系统的稳定性。仿真结果显示,所设计的太阳能两轮电动车能量控制策略能够很好地保持直流母线电压恒定,满足系统设计需求。
The changing environment of two-wheeled solar electric vehicles leads to unstable output of solar panels.In order to ensure the stable operation of the motor load,the energy control of two-wheeled solar electric vehicle was studied.Based on the principle of sliding mode variable structure control,a control strategy of tracking the maximum power output point of solar cell was designed.At the same time,a new DC/DC converter was designed to realize the joint power supply of solar cells and batteries.The MATLAB simulation platform was set up to test the system's stability by changing the DC bus end load.The simulation results show that the designed energy control strategy can keep the DC bus voltage constant and meet the design requirements of the system.
