Based upon a uniform counterpart, a gridpoint model with variable resolution is presented. It has been proved that if the former model satisfies certain conditions, has properties of mass and energy conservation and keeps the conversion between kinetic and potential energy consistent to that in the continuous transformation, then the latter model will possess the same properties and conversion as well. Further, transforming the former into the latter needs a small amount of computational operation.

In this paper, according to the energy consistent principle and the deformation constrained equations, the consistent linear dynamic model in finite dimentions of a horizontally slewing inextensible Euler Bernouli beam, taking into account the dynamic stiffening effect and a tip payload, is derived by using assumptive modes method. To achieve the joint angle trajectory tracking, the input output partial linearing control method is used to decouple the nonlinear model and to generate the control input for the joint angle desired trajectory. To suppress the simultaneous elastic vibratios in movement, an elastic stabilization is designed by using the LQR control method. Numerical simulation results are presented to show the effectiveness of the proposed control strategy.

针对轴向不伸长的Euler-Bernouli梁,采用假设模态法,根据能量一致性原理,利用变形约束方程的小变形假设条件,对带有末端荷载的柔性机械臂,推导出考虑动力刚化(dynamicstif-ening)影响的柔性机械臂有限维一致线性化动力学方程。为实现柔性机械臂关节转角运动轨迹的精确跟踪,采用基于输入输出部分线性化的控制方法设计非线性控制器,对该非线性动力学模型进行解耦并产生理想关节转角运动轨迹的控制输入。采用线性系统最优状态反馈控制规律设计弹性模态稳态器抑制弹性体的振动。数值仿真验证了该控制策略的有效性。
