摘要
本文讨论了一种新的挠性悬挂防摆控制系统。挠性构件因工作中的摇摆现象已不能适应工程机限工作速度进一步提高的要求。文中探讨了利用机电一体化技术控制摆动幅度的可能性。在相似理论基础上设计了一个桥式吊车的缩尺摸型,并对它进行了试验。利用状态变量方法和二次型性能指标最优控制理论提出了控制系统的控制算法。用 MCS—51单片机实现了这种算法。对试验数据的分析表明这种设想是可行的,并对进一步研究进行了讨论。
In view of the flexible elements on construction equipments cannot suit the further increasing of the working speed of such equip-ments,the author suggests that the problem may be solved usingmechatronical techniques.In this paper,a new antisway measureon flexible suspension is discussed.A scale model of an 8.0ton bridge crane based on“similar theory”has been made.Anoptimum control algorithm is developed by using the state vari-able method and the quadratic form performance parameters.Thisalgorithm has been realized on a single chip microprocessor MCS-51.Analysis of the experimental data shows that this controlsystem is feasible and proposals for future work are advanced.
