The invention discloses a driving control device of a high voltage generator for a paver and a control method. The driving control device comprises a detection module, a controller, a PID intelligent adjusting module, a driving module, a hydraulic pump, a proportion valve and a hydraulic motor. By use of the multi-sensor fusion technology, states of the current hydraulic system are detected; and the BP neural algorithm is introduced in the normal PID controller, so high precision control is achieved, and an intelligent control of the high voltage generator for the paver is achieved. The proportion valve of the high voltage generator is used to controlling carrying out self-learning calibration on the current from the smallest to the biggest, and carrying out segmentation control on rotation speed of the high voltage generator, so the requirement of enough small dynamic errors and steady-state errors of the system are met, it is ensured that the overshoot of the system is as low as possible and the no-load and on-load steady-state rotation speed of the high voltage generator is controlled within the required range; stability of the rotation speed of the high voltage generator is improved; and the service lifetime of the high voltage generator is prolonged.

technical field [0001] The invention relates to a driving control device and a control method of a high-voltage generator for a paver, and belongs to the technical field of engineering machinery. Background technique [0002] With the development of highway construction, more and more electric heating systems of pavers use hydraulic motors to drive high-voltage generators, so higher requirements are put forward on how to control the speed of high-voltage generators. In the prior art, the driving device of the high-voltage generator for paver uses a conventional PID to control the high-voltage generator, which can initially stabilize the rotation speed of the generator, but there are still certain defects: [0003] 1. The control accuracy, self-learning and self-adaptive ability of the existing device, as well as the anti-interference ability and the robustness of the system are poor; the high-voltage generator speed overshoot of the paver is large, and the intelligence of t...
