【摘要】：根据粘弹性材料耗能减振性能较好的特点,针对高频扰动、冲击扰动,本文提出了主动粘弹性控制的方法,定义了主动粘弹性控制技术的基本架构.根据粘弹性材料的耗能计算模型,提出了粘弹性控制律的选取原则.结合广义Maxwell模型,提出了3种粘弹性控制律(viscoelastic control law,VCL).并将粘弹性比例 微分(proportional derivative,PD)控制、粘弹性比例 积分 微分(proportional integral derivative,PID)控制、粘弹性自抗扰控制(active disturbance rejection control,ADRC)应用到常见的二阶系统中.研究结果表明,主动粘弹性控制技术抗高频扰动、抗冲击扰动的性能特别优异.由于主动控制的响应速度快,主动粘弹性控制的抗扰性能好,本文提出了主动控制与主动粘弹性控制相切换的控制方法,并对切换控制策略进行了研究.研究结果表明,切换控制可同时兼顾抗扰性能与响应速度.
[Abstract]:According to the characteristics of good energy dissipation and vibration absorption of viscoelastic materials, this paper presents an active viscoelastic control method for high frequency disturbance and shock disturbance, and defines the basic framework of active viscoelastic control technology. According to the energy dissipation model of viscoelastic materials, the selection principle of viscoelastic control law is put forward. Combined with the generalized Maxwell model, three kinds of viscoelastic control laws (viscoelastic control law,VCL) are proposed. Viscoelastic proportional differential (proportional derivative,PD) control, viscoelastic proportional integral differential (proportional integral derivative,PID) control and viscoelastic autodisturbance rejection control (active disturbance rejection control,ADRC) are applied to common second-order systems. The results show that the active viscoelastic control technique has excellent performance in resisting high frequency disturbance and shock disturbance. Due to the fast response speed of active control and the good immunity performance of active viscoelastic control, this paper proposes a phase switching control method between active control and active viscoelastic control, and studies the switching control strategy. The results show that both immunity performance and response speed can be taken into account in switching control.
