摘　　要：为了缩短混合动力汽车起步时间,设计了汽车电机分数阶模糊PD+I控制器,并对电机转速启动效果进行仿真验证。给出了非线性车辆动力学模型,根据牛顿第二定律,推导出非线性混合动力汽车动力学方程式。针对模糊PID控制系统进行改进,设计了汽车电机分数阶模糊PD+I控制器。为了提高控制系数自适应响应速度,采用改进黑洞算法对其进行优化,给出了电机控制系统的优化流程。为了检验优化后的控制系统输出效果,采用MATLAB软件对混合动力汽车电机响应速度进行仿真,并且与优化前输出结果进行对比。结果显示:优化前,混合动力汽车电机自适应调节时间较长,受到外界干扰时,电机转速变化幅度较大;优化后,混合动力汽车电机自适应调节时间较短,受到外界干扰时,电机转速变化幅度较小。采用改进黑洞算法优化分数阶模糊PD+I控制器,可以提高电机响应速度,缩短混合动力汽车起步时间。In order to shorten the starting time of hybrid electric vehicle,a fractional order fuzzy PD+I controller is designed,and the starting effect of motor speed is verified by simulation.According to Newton's second law,the nonlinear vehicle dynamics equation is derived.In view of the improvement of fuzzy PID control system,a fractional order fuzzy PD+I controller is designed.In order to improve the adaptive response speed of the control coefficient,the improved black hole algorithm is used to optimize it,and the optimization process of the motor control system is given.In order to test the output effect of the optimized control system,the response speed of the hybrid electric vehicle motor is simulated by MATLAB software,and the results are compared with those before the optimization.The results show that:before the optimization,the adaptive adjustment time of the hybrid electric vehicle motor is longer,when it is disturbed by the outside world,the change range of the motor speed is larger;after the optimization,the adaptive adjustment time of the hybrid electric vehicle motor is shorter,when it is disturbed by the outside world,the change range of the motor speed is smaller.Using the improved black hole algorithm to optimize the fractional order fuzzy PD+I controller can improve the response speed of the motor and shorten the starting time of the hybrid vehicle.
