摘要
针对悬索结构强非线性和大滞后的特点,提出了一种基于铰接的弹簧阻尼系统柔性悬索的离散模型,此模型包含了悬索刚度、内部阻尼、重力及风扰等信息.在此基础上,建立了由悬索和控制器组成的悬索控制系统的数学表达式,并采用四阶Runge Kutta方法对风扰作用下的悬索控制系统进行了数值仿真,表明此模型和控制方法的有效性.
According to the strong nonlinearity and lag of the cable feed system, a discrete model, consisting of a jointed spring-damping system, is proposed. The cable stiffness, internal damping, joint friction, gravity and wind disturbance are included in this model in order to give an accurate description of the cable, on the basis of which the mathematical representation of a cable feed mechanism and a controller is developed, and a series of simulation is carried out with the 4th order Runge Kutta method. Results show the effectiveness of this model and controller.
