Embodiment

[0117] figure 1 It is a schematic structural diagram of a truck crane, including a turntable 1, a boom 2, a luffing cylinder 3, a lifting weight 4 and a lifting rope 5. The turntable 1 realizes the horizontal movement of the hoisting weight 4 rotating around the central axis of rotation of the crane through a slewing mechanism. The boom 2 includes a plurality of mutually socketed telescopic booms, and the telescopic boom generates relative motion through the telescopic action of the telescopic drive mechanism, thereby changing the length of the boom 2 to adjust the working radius of the truck crane. One end of the luffing cylinder 3 is hinged with the turntable 1, and the other end is hinged with the boom 2. By adjusting the length of the luffing cylinder 3 in the luffing mechanism, the boom 2 is further articulated around the luffing cylinder 3 and the turntable 1 in the vertical plane. Rotate at the point to change the elevation angle of the boom 2, thereby changing the lif...

Abstract

The invention provides an automobile crane parameter type recognition method and a response error control method and system in order to avoid the phenomenon that an automobile crane is overloaded due to misjudgment of indefinite parameter types. The crane parameter type recognition method comprises the three steps for determining the type of working parameters of an automobile crane. The response error control method comprises the five steps for acquiring the amplitude movement response error value of the automobile crane and adjusting the pressure of an oil cylinder according to the error value, so that control over response errors is realized. The system adopted for the response error control method comprises an indefinite parameter recognition subsystem and a response error control subsystem which are connected with each other. By specifically implementing the methods, control over the response errors of the automobile crane is realized. The crane parameter type recognition method and the response error control method and system have the beneficial technical effects that the type of the working parameters of the automobile crane can be recognized, so that the response errors of the automobile crane are controlled more reasonably and optimally.

Description

technical field [0001] The invention belongs to the field of control technology, in particular to the field of crane control, in particular to the field of truck crane uncertainty parameter identification technology and control equipment, specifically, a method for identifying parameter types of truck cranes, a response error control method and a system. Background technique [0002] At present, the structural size and load size are often regarded as deterministic parameters for the analysis of the response of the truck crane to the luffing motion. However, due to design errors, manufacturing errors, assembly errors, unpredictable external stimuli (such as wind), and changes in the positions of different joints during the movement (such as the hinge between the boom and the turntable, [0003] The joint of the boom and the luffing cylinder, the joint of the luffing cylinder and the turntable), etc., in the actual use environment, the structural parameters and load parameters...
