The present disclosure relate to a fault diagnosis method, including: collecting at least one set of original data of the high voltage generator during operation, each condition attribute in a condition attribute set corresponding to one piece of original data; pre-processing the original data to obtain pre-processed data and generating a decision table; performing an attribute reduction based on the decision table to obtain a reduced condition attribute set and a reduced decision table; generating a decision tree model according to the reduced decision table; generating a decision forest model according to at least one decision tree model; obtaining a fault type and a fault level according to the decision forest model; determining an acceptable level of the fault according to the fault level and a frequency of occurrence of the same type of fault, and sending the fault type and the acceptable level to the display terminal.

Fault diagnosis method and system for high-voltage generator

A method for controlling a power supply includes: acquiring working state information of the power supply in a current operation; determining whether a state value of the power supply in the current operation satisfies a preset condition according to the working state information; setting a first control strategy for controlling the current operation of the power supply as a second control strategy when the preset condition is satisfied; storing the state value in the current operation and the first control strategy of the power supply in the current operation when the preset condition is not satisfied, and modifying the first control strategy to obtain the second control strategy according to an adjustment strategy; and loading the second control strategy from the machine-learning control circuitry in next operation, and controlling the next operation of the power supply according to the second control strategy.
