| 内容記述 | An adaptive nutrient control method for a plant factory is proposed. The method is based on a Reinforcement Learning modified for a target in which one state never comes back during a single episode and a reward is given after a very long delay. In application such as plant growth control, one episode takes a very long time period, and a rapid convergence to a prospective control solution is essential, whilst an extensive exploration is needed since there is usually no precise model available. A method like Reinforcement Learning is useful for a problem having no reference model. But a necesity of exploration does not match the need for rapid convergence, and a new balancing method is needed. In this research, an avarage reward distribution method is proposed, which is similar to the Profit Sharing method but affects more extensively to find much prospective early solutions, whilst guaranteeing to converge into a rational solution in a long run. An experiment is conducted in a simple plant factory system, which shows that at least standard Reinforcement Learning is insufficient for this type of problem. Computer simulations show that the method has good effects comparing to a standard RL, and a profit sharing method. | |||||
