N2 - The evolution of the hydrostatic transmission system from mechanical systems to electronically controlled systems creates opportunity for improvements in efficiency through the use of intelligent control algorithms. In systems for which the prime mover is an internal combustion (IC) engine, overall system efficiency depends greatly on the prime mover's operating conditions. The use of variable displacement pumps can add a degree of freedom and allow engine operation to be optimized. However, this strategy requires a desired engine power value based on operating states and load references. This paper proposes a novel solution to this problem by using a dynamic engine power demand estimate to meet steady-state load demands using minimal engine power.
