Machine learning device for teaching in a gain optimization, engine control device with machine learning device and machine learning method

摘要

A machine learning apparatus according to an embodiment learns a condition for setting a current gain parameter in an electric machine control and includes: a condition monitoring unit acquiring the current current, and monitoring an integral gain function and a proportional gain function in a current control loop and which state variable including the integral gain function, the proportional gain function, and at least one the following quantities: amount of overshoot, amount of undershoot and rise time of the instantaneous current in response to a stepwise torque command; and a learning unit that learns the condition for setting the current gain parameter according to a training data set from the state variables.
