The invention relates to a control method for a swing angle of an unmanned crown block based on an online genetic algorithm and belongs to the technical field of metallurgical automation. The technical scheme of the invention is as follows: the control method comprises the following steps of calculating fitness of the genetic algorithm and carrying out genetic algorithm selection, crossing geneticalgorithm, genetic algorithm variation, genetic algorithm convergence judgment and genetic algorithm decoding; and updating and iterating a genetic chromosome according to a swing angle set value ofthe crown block and an on-the-spot actual swing angle value and transmitting optimized P, I and D parameters which are stored in an oracle database of the unmanned crown block to a PID controller of the unmanned crown block to adjust the speed of the crown block. The control method has the beneficial effects that the size of the swing angle of the unmanned crown block during operation is controlled within a permitted error range, so that accurate stocking of steel coils in a warehouse and the safety of a steel coil transportation process are guaranteed effectively.
