The invention relates to a self-learning synchronous corrosion control system and a self-learning synchronous corrosion control method. The system comprises operating control equipment, wherein the operating control equipment is connected with at least two driving units through a synchronous correction controller; each driving unit is connected with corresponding driven equipment in a driving mode; a position detector is arranged on each driven equipment; and the signal output end of each position detector is connected with the synchronous corrosion controller. The system automatically learns the driving parameter of each driving unit on line and respectively adjusts the control parameter of each driven / driving unit continuously according to the operating distance and the real-time position obtained through on-line measurement of a range pole driving unit and each driven / driving unit, and adjusts the corrosion control quantity of each driven / driving unit according to the position deviation value of the range pole driving unit and each driven / driving unit, so that all the driven / driving units and the range pole driving unit operate synchronously, and the synchronous correction controller with the self-learning function can realize synchronous correction control more stably and precisely.
Description
technical field [0001] The invention belongs to the technical field of synchronous deviation correction motion control of multiple operating drive units, and relates to a self-learning synchronous deviation correction control system and method. Background technique [0002] When two or more operating drive units drive an associated mechanism and load at the same time, we need these multiple drive units to realize synchronous operation. For example, when a crane with multiple trolleys and hoisting mechanisms is used to lift loads, the lifting and horizontal movement of the trolleys need to move synchronously. In addition, when the long-span gantry crane is running on the rails on both sides, the drive units on both sides need to maintain a high degree of synchronization, so as to avoid the deviation of the movement on both sides of the crane and the rail gnawing phenomenon of the crane wheel. [0003] In order to ensure the synchronous movement of multiple drive units, it is...
