Summary

In this study, optimal control of heat stress was applied in order to minimize the water loss of fruit during storage using an intelligent control system, which consists of a decision system and a feedback control system. In the decision system, the dynamic change in the rate of the water loss, which is affected by temperature, is first identified using neural networks. The optimum l-step set points of temperatures that minimize the rate of the water loss are sought through simulations of the identified neural-network model using genetic algorithms. A temperature operation, rising first to the highest level and then dropping to the lowest level in the given range, provided a lower rate of water loss than by keeping constant at the lowest level throughout the control process.
