针对小车一级倒立摆的起摆控制,以DRNN神经网络作为辨识器,在线自适应调整PD控制器的两项参数。在起摆范围相同的情况下,DRNN神经网络控制的倒立摆系统其模型参数变化范围为-50%~30%,传统PD控制倒立摆系统其参数变化范围为-40%~20%。结果表明,基于DRNN神经网络的PD控制器比传统的PD控制器具有较强的抗干扰能力和自适应能力,系统鲁棒性增强,效果明显优于传统的PD控制器。 相似文献

We propose a control law to swing-up the acrobot from an initial domain to a neighbourhood of the vertically upward equilibrium position. The methodology involves reducing the system to a one degree-of-freedom system, much like a simple pendulum, evolving on a critical value of the energy level set. The system is guaranteed to converge to a neighbourhood of the upward equilibrium position about which a linear feedback controller is switched on to stabilize the system. 相似文献

Research problems in clothing simulation 总被引:1,自引:0,他引:1
Clothing simulation and animation are of great importance in computer animation. If cloth simulations could be improved to the point that they could generate realistic cloth motion in real-time, they would find uses in many aspects of daily life such as in fashion design and manufacturing. The area of cloth simulation and animation is full of technical challenges: creating more realistic results, achieving faster run-times, and developing methods capable of constructing and simulating more complex garments. This paper provides an overview of the key procedures involved in the creation of clothed characters, describes the current state-of-the-art techniques, and proposes the research problems that most require further study. Three technical aspects of cloth simulation are considered in this paper: garment construction, physically based simulation, and collision resolution. 相似文献

在计算机仿真中,二,三维演示展现依赖于对仿真实体属性的获取,传统的二,三维演示只能显示仿真实体的部分属性,且不能随意添加新的仿真实体,这极大地破坏了仿真实体属性的完备性,影响了二维显示效果.在传统做法的基础上寻求改进,提出一种动态创建实体对象,运用迭代方法更新属性的技术,实现了任意数目仿真实体属性的显示. 相似文献
