结合电子商务的影院经营新策略

在现代社会中随着科技的发展，各种替代品迅速诞生，影院已经日渐没落。难道影院真的会成为“昨日黄花”？我不这样认为。在网络时代到来的今天．只要把影院经营密切地与因特网联系起来，同时提高服务质量，影院重振雄风只是时间问题。     

图像处理中自适应数学形态学的研究

实际图像处理中当视场的变化引起目标变形时,固定大小的形态学算子很难达到较好的处理效果。研究了利用距离变换自适应地调整结构元大小的方法,即根据图像的不同位置来调整结构元素的大小,从而实现图像的形态学运算,并由此推导出了快速计算方法,最后测试了这种新算法的有效性。实验结果表明,该算法取得了较为理想的效果。

Lyapunov‐stable discrete‐time model reference adaptive control

Discrete‐time model reference adaptive control (MRAC) is considered with both least squares and projection algorithm parameter identification. For both cases complete Lyapunov proofs are given for stability and convergence. The results extend the approach of Johansson (Int. J. Control 1989; 50 (3):859–869) to include Lyapunov stability for MRAC when the normalized projection algorithm is used for parameter identification. Copyright © 2005 John Wiley & Sons, Ltd.

空间机器人姿态与末端抓手协调运动的鲁棒自适应控制

本文讨论了载体姿态受控、位置不受控制的漂浮基空间机器人协调运动的控制问题。借助于虚拟扩展系统的输入与输出,得到了一组关于惯性参数呈线性函数关系的系统控制方程。以此为基础,针对空间机器人系统中不确定参数与未知参数并存的复杂情况,设计了载体姿态与末端抓手惯性空间轨迹协调运动的鲁棒自适应控制方案。利用两杆空间机器人系统进行了系统仿真运算,仿真结果证实了上述控制方案的有效性。由于对系统待估计参数作了分类,并充分利用系统信息对系统不确定参数采用保持鲁棒性而不是在线估计的方法,提到的控制方案具有计算量小的优点,有助于缓解机载计算机运算能力有限的矛盾。

Generation of adaptive gait patterns for quadruped robot with CPG network including motor dynamic model

This paper describes the generation of adaptive gait patterns using new Central Pattern Generators (CPGs) including motor dynamic models for a quadruped robot under various environments. The CPGs act as the flexible oscillators of the joints and adjust joint angles to required values. The CPGs are interconnected with each other and sets of their coupling parameters are adjusted by a genetic algorithm so that the quadruped robot can realize stable and adequate gait patterns. Generation of gait patterns results in the formation of the CPG networks suitable for the formation of not only a straight walking pattern but also of rotating gait patterns. Experimental results demonstrate that the proposed CPG networks are effective for the automatic adjustment of the adaptive gait patterns for the tested quadruped robot under various environments. Furthermore, the target tracking control based on image processing is achieved by combining the general gait patterns. © 2006 Wiley Periodicals, Inc.

Minimum switching control for adaptive tracking

The switching adaptive control method has been used for quite a few years to solve the adaptive stabilization and model reference adaptive control problems. However, a serious problem with the switching control method is that the number of ‘candidate’ controllers can potentially be very large, especially for multi‐input–multi‐output systems. In this paper, we consider a class of minimum‐phase multi‐input–multi‐output plants with some mild compactness assumptions. Given any polynomial reference input, we provide a switching control law which guarantees exponentially stability of the closed‐loop system with exponential tracking performance. The main contribution of the paper is that we give the minimum number of candidate controllers required for switching. In particular, the number is equal to 2 for single‐input–single‐output plants (one for each sign of the high‐frequency gain), and is equal to 2^m for m‐input–m‐output plants. That is, the number is independent of the degree and the relative degree of the plant. Copyright © 2006 John Wiley & Sons, Ltd.
