摘　　要：针对磁流变减摆控制参数整定方法效率低、耗时长、精度差问题,提出一种基于改进樽海鞘群算法(Modified Salp Swarm Algorithm,MSSA)的减摆控制优化方法。首先,针对领导者更新引入精英个体杂交变异策略,提高全局搜索能力;然后,对于跟随者更新采取自适应差分变异策略,加快优化效率;最后,以摆幅最小、摆振收敛时间最短为优化目标,将改进樽海鞘群算法应用于磁流变减摆控制参数整定。基于标准函数的性能测试表明,与樽海鞘群(Salp Swarm Algorithm,SSA)、高级萤火虫(Advanced Firefly Algorithm,AFA)、粒子群(Particle Swarm Optimization,PSO)和遗传算法(Genetic Algorithm,GA)相比,改进算法的收敛精度更高,优化效率更快,性能更稳定。优化仿真实验进一步表明,相较SSA,AFA,PSO,GA优化的减摆控制系统,该整定方法优化用时短,能够使机轮平均摆幅减少4.24%以上,并确保摆振在规定时间内收敛,减摆效果更优。Confronted with inefficient,time-consuming and inaccurate process in optimizing control parameters of magnetorheological shimmy damper,an optimization method based on Modified Salp Swarm Algorithm(MSSA)is proposed.Firstly,the elite individual hybrid mutation strategy for leader update is introduced to improve global search ability.Then,the adaptive differential mutation strategy for follower update is adopted to speed up optimization.Finally,to minimize the swing and convergence time of shimmy,MSSA is applied to optimizing the control parameters of MR shimmy damper.Performance tests based on standard functions show that the modified algorithm turns out more accurate,efficient and stable,compared with Salp Swarm Algorithm(SSA),Advanced Firefly Algorithm(AFA),Particle Swarm Optimization(PSO)and Genetic Algorithm(GA).The simulation experiment demonstrates that the optimization time is shorter by using this method.And it can reduce the average lateral displacement of wheel by more than 4.24%and ensure that the swing vibration converges within the specified time with better swing reduction effect.
