塔吊高效运行控制器算法研究

目前国内外的塔吊装置都是以安全监控为主,针对实现塔吊高效运行的目的采用双闭环控制算法,其中外环即电流环只是以跟踪性能为主,所以采用常规PID。对于内环即转速环,采用模糊自适应PID算法,除了可以使系统在输入量为时变时有较好的动态性能之外,当系统的参数发生变化即受到干扰或负载变化的情况下,系统可以拥有较好的调节性能。从而极大的提高了工作效率。另外在塔吊的起身机构从启动到稳定的快速平滑的运行采用准时间最优控制算法来实现。最终实现辅助塔吊进行高效运行的目的,即完成对塔吊高效运行控制器的设计目的。

Crane Efficient Operation Controller Algorithm Research

Safety monitoring of crane devices is a high priority in China and abroad. In order that the crane works effectively with a double closed loop control algorithm, the outer ring is current loop is designed for mainly tracking purposes, so the conventional PID is used. For the inner ring, also known as the rotation speed loop, the fuzzy adaptive PID algorithm is used; in addition to being able to make the system have good dynamic performance when different time variables are inputted, when the system parameters change due to interference or load change, system can have good adjustment performance. Thus the work efficiency is greatly improved. In the crane and other rising mechanisms, a time-accurate optimized control algorithm is used to achieve a smooth transitional operation from start to stable running. Ultimately the efficient operation of the crane, the optimal speed and efficient implementation are achieved. The design objective of an efficient crane controller is achieved.
