本文研究一种索缆类结构系统动态响应的有源的轴向主动刚度控制技术。通过沿缆索轴向设计产生一个主协动态位移导致缆索系统的横向刚度变化并产生附加阻尼,使缆索的横向振动幅值减小。通过模拟装置实验,验证了开环地施加这种控制,可获得预计的减少振动的效果。

This paper presents the method to deal with numerical time response analysis of a moving clamp that is running over a roller battery support of a cable transport system, which is a dynamics procedure involving time and form varying nonholonomic kinematics constraints as well as inter-excitation between parts. The numerical results are compared with test ones.

A dynamic model is developed for a cable supporting roller battery of cable transport systems, which allows the calculation of eigenfrequencies and modes under the restoring action of a pretensioned cable and subsequently enables the response investigation during the successive passage of a clamp (with supported vehicles) over the rollers. An analytical method is developed and the analytical results are compared with test results: the calculated eigenmodes and eigenfrequencies are in satisfying agreement with our test results.

【期刊论文】Multi-objective H∞ optimal control for four-wheel steering vehicle based on yaw rate tracking

In this paper, a lateral controller is designed for four-wheel steering (4WS) vehicle. The linear lateral dynamics of 4WS vehicle is deduced and then analyzed aided with three-dimensional graphs. To improve vehicle handling and stability at high speed, a multi-objective H∞ optimal control algorithm is presented while yaw rate is the only feedback signal. Simulation shows that the sideslip angle, yaw rate and lateral acceleration of the 4WS vehicle follow and maintain preferable characteristics. The 4WS vehicle is agile and consistent with the steering input and does not understeer excessively.
