DETERMINATION OF Q-FUNCTION OPTIMUM GRID APPLIED ON ACTIVE MAGNETIC BEARING CONTROL TASK
Original language description
Active magnetic bearing control task can be successfully solved using reinforcement learning based method called Q-learning. The main problem to solve is the convergence speed. Two-phase Q-learning can be used to speed up the learning process [2]. Efficient prelearning phase uses mathematical model, following tutorage phase runs on real system and uses conventional Q-learning. This method can increase learning speed significantly, however there are still certain issues remaining to solve in order to impprove the overall performance of the controllers based on Q-learning. When the table is used as Q-function approximation, the learning speed and precision of found controllers depend highly on the Q-function table grid properties. The paper is denoted tothe determination of optimum grid with respect to the properties of controllers found by given method. Comparison of the results with performance of referential PID controller is included. Obtained results indicate that using nonlinear g
