The invention provides a motor health management method and
system based on
full life cycle monitoring, and the method comprises the steps: firstly collecting motor multi-source sensor data, and mapping the motor multi-source sensor data into a coordinate point in a low-dimensional health
state space through a manifold learning model, so as to represent the comprehensive health state of the motor multi-source sensor data; and on the basis of the expert strategy
database, a health cost function associated with the health coordinates is constructed by adopting
inverse reinforcement learning and is used for quantifying health loss of different operations. And a
decision model is constructed, and the model is trained through an
optimal control algorithm, so that an operation strategy capable of minimizing the total health cost of the whole life cycle of the motor can be found out. In actual operation, the
system determines current health coordinates in real time, generates an optimal operation strategy by using a
decision model in combination with future task requirements, and analyzes the optimal operation strategy into specific
control parameters to be issued and executed. According to the method, active health decline path management and closed-
loop control of the motor can be realized, so that dynamic optimal balance between the performance and the service life of the motor is realized.
