Abstract

<p>This paper deals with the development of a 5kW ultra-compact binary power generation plant using low temperature difference thermal energy and a control system design method with high control performance using low electrical power consumption actuator. It is necessary to save electrical power consumption of manipulated variables in the operation of the plant to realize the ultra-compact binary power generation. A three-input and two-output transfer function model that has one more manipulated variable of very low electrical power consumption than the number of controlled variable to improve control performance by using a non-squared (NS) decouple PID control system is proposed, and its strategy as a method of control system design is introduced. The model is presented with a linear transfer function that represents a dynamic characteristic at nearby operating point of the plant. The control results are compared with the other control systems through simulations to verify the validity of the proposed control system.</p>
