摘　　要：针对声共振混合器加速度控制精度问题,提出了一种改进麻雀算法(ISSA)优化的径向基函数神经网络(RBFNN)PID加速度控制方法。首先通过阶跃响应曲线辨识出加速度模型,进而通过引入Tent混沌初始化种群和线性动态惯性权重优化发现者位置等对麻雀搜索算法进行改进,然后将ISSA用于RBFNN参数的优化,最后将优化后的RBFNN-PID应用于加速度的仿真测试,并与其他算法进行比较。仿真结果证明,开发的ISSA收敛速度和寻优能力要优于其他算法,用ISSA优化RBFNN-PID加速度控制,能够有效抑制系统超调量,提高系统控制速度、精度和稳定性。实验结果表明,与对比算法相比,基于ISSA优化的RBFNN-PID加速度控制系统展现出更优越的控制性能与自适应能力,对声共振混合器加速度控制具有较大的实用价值。Given the control accuracy problem of the resonant acoustic mixer′s acceleration,a radial basis function neural network(RBFNN)PID optimized by an improved sparrow search algorithm(ISSA)method is proposed to control acceleration.Firstly,the acceleration model is identified through the step response curve.Secondly,the sparrow search algorithm is enhanced by introducing a Tent chaos initializing population and a linear dynamic inertial weight method for updating the discoverer′s position.Thirdly,ISSA is then applied to optimize the parameters of the RBFNN.Finally,the optimized RBFNN-PID is employed for the simulation test of acceleration and compared with other traditional algorithms.The simulation results show that the convergence speed and optimization ability of the developed ISSA are superior to other algorithms.It is found that the RBFNN-PID acceleration control optimized by ISSA can effectively suppress system overshoot and improve system control speed,accuracy,and stability.Experimental results show that,compared with the comparison algorithms,the RBFNN-PID acceleration control system optimized by ISSA demonstrates superior control performance and adaptive capability,providing a great practical value for the acceleration control of the resonant acoustic mixer.
