摘　　要：电动加载系统的突出优点是加载跟踪速度快,但加载过程中系统多余力能否快速消除是制约加载精度、影响加载系统动态品质的最重要因素。常规PID控制难以满足电动加载系统对高精度和快速性的要求,而模糊自适应PID控制能够解决这个难题,实验证实了系统采用模糊自适应PID算法后明显提高了加载精度和响应速度。The advantage of electric loading simulation system is that it can track the load curve more quickly. Whether eliminating the Superabundant torque quickly or not during operating is the key issue of determining the precision and dynamic quality of system, Classical PID control is hard to satisfy the demand of high precision and speediness, while fuzzy adaptive PID control can solve this problem. The system＇ s loading precision and dynamic performance after adapting fuzzy PID strategy improves obviously through experiment.
