This paper deals with: 1) the optimal control concept of a farm power-transmission-equipment system, 2) the optimal control system design, 3) the experimental system for proving the possibility of the control System, and 4) the testing results.
The hardware of this experimental system consists of four subsystems such as an engine-transmission-load subsystem, a measuring subsystem, a controller unit subsystem and a computer subsystem. The softwares for the data acquisition, optimal calculations and optimal controlling are also developed.
The results of the optimal control testing show that the engine is always able to work in the optimal region of the lowest specific fuel consumption by controlling the engine speed and the shifting ratio of the transmission system, through the application of this control system on a farm power-transmission-equipment system.
