【摘要】：工程机械控制器的研究是目前工程机械控制领域的热点，课题提出的通用型监控系统是对当前控制器研究的一个创新。本文对控制策略进行深入研究，，也是对工程机械通用型控制器设计的延续。模糊控制已经成为工业控制中常见的控制方式，但是模糊控制算法中不同模糊合成关系对工程控制上带来的影响，并没有相关的研究，本文应用“最大-最小”和“最大-代数积”两种模糊算法和双输入单输出模糊推理规则开展模糊控制器的研究和设计，并进行了仿真试验研究和分析比较。对控制对象重型工程机械中的液压伺服位置控制系统进行了深入的研究，分析了系统中各个组件的特性，进而建立了系统的数学模型。为了探索适宜的控制策略，对比例控制、PID控制控制和模糊控制系统进行了仿真试验研究。设计了模糊控制器，并对不同模糊控制算法进行了分析比较，再通过仿真分析模糊控制策略在该系统应用的可行性。
[Abstract]:The research of construction machinery controller is a hot spot in the field of construction machinery control at present. The general monitoring system proposed in this paper is an innovation in the research of current controller. The control strategy is deeply studied in this paper. Fuzzy control has become a common control mode in industrial control, but different fuzzy synthesis relations in fuzzy control algorithm have brought about the influence on engineering control. There is no related research. In this paper, two fuzzy algorithms, "maximum-minimum" and "maximum-algebraic product" and double input, single output fuzzy inference rules are used to study and design the fuzzy controller. The hydraulic servo position control system in heavy construction machinery is studied deeply, and the characteristics of each component in the system are analyzed. Then the mathematical model of the system is established. In order to explore the appropriate control strategy, the proportional control pid control and fuzzy control system are simulated and studied, and the fuzzy controller is designed. Different fuzzy control algorithms are analyzed and compared, and the feasibility of applying fuzzy control strategy to the system is analyzed by simulation.
