摘　　要：为了提高田径运动员腿部爆发力的量化分析能力,提出一种基于模糊滑模导纳控制的田径运动员腿部爆发力长时效应建模方法.构建田径运动员腿部爆发力学模型,采用运动学建模方法分析田径运动员腿部爆发力的力矩特性和动力学特性;构建田径运动员腿部爆发力长时效应控制约束对象模型,采用被动训练模式和主动训练模式结合的方法,进行田径运动员腿部爆发力量化分析;提取田径运动员腿部爆发力输出的末端位姿特征,结合模糊滑模导纳控制方法,实现田径运动员腿部爆发力长时效应建模.仿真结果表明,采用该方法进行建模的准确度较高,对田径运动员腿部爆发力的量化分析能力较好,提高了田径运动员腿部训练的针对性和有效性.In order to improve the quantitative analysis ability of leg explosive force of track and field athletes, a modeling method of long time effect of leg explosive force of track and field athletes based on fuzzy sliding mode admittance control is proposed. This paper constructs the leg explosive force model of track and field athletes, analyzes the torque and dynamics characteristics of the leg explosive force of track and field athletes by using the kinematics modeling analysis method, and constructs the constraint object model of the long time effect control of the leg explosive force of track and field athletes. By combining passive training mode with active training mode, the quantitative analysis of the leg explosive force of track and field athletes is carried out, and the terminal position and pose characteristics of the leg explosive force output of track and field athletes are extracted, and the fuzzy sliding mode admittance control method is combined with the fuzzy sliding mode admittance control method. The model of long time effect of leg explosive force of track and field athletes is realized. The simulation results show that the accuracy of modeling by this method is high, and the quantitative analysis ability of leg explosive force of track and field athletes is better than that of track and field athletes. All of these improve the track and field athlete in the leg training pertinence and effectiveness.
