    摘要:

    針對(duì)柔性機(jī)械手研究中未將控制器和機(jī)械結(jié)構(gòu)之間的耦合同時(shí)加以考慮的問(wèn)題,在整體優(yōu)化目標(biāo)下,通過(guò)使用適用于各種幾何約束的自適應(yīng)迭代算法來(lái)獲取機(jī)械臂狀態(tài)和控制器參數(shù),,以結(jié)構(gòu)優(yōu)化為外循環(huán),以LQR控制律優(yōu)化為內(nèi)循環(huán),,設(shè)計(jì)了全局優(yōu)化設(shè)計(jì)方法,將柔性機(jī)械手機(jī)械結(jié)構(gòu)的設(shè)計(jì)與控制算法的設(shè)計(jì)有機(jī)結(jié)合在一起,。并以單關(guān)節(jié)柔性臂的設(shè)計(jì)為例進(jìn)行了仿真,,仿真結(jié)果表明,將控制律與結(jié)構(gòu)優(yōu)化綜合考慮的方法有效,、可行,。

    Abstract:

    Under the integration optimization object, the beam shape and controller parameters were obtained by using an adaptive iterative algorithm with the accommodation of various geometrical constraints to consider the coupling between the controller and the mechanical structure of a flexible manipulator concurrently. The global optimization method was designed to combine the physical construction design with control algorithm by using the structure optimization as the outer-loop and the linear quadratic regulator(LQR) control as inner-loop. The simulation work of a single link flexible beam was done. The simulation results showed that the integration method to consider the control law and the structure optimization synthetically is effective and feasible.
