Optimized Control Strategy of Hybrid Skidder based on Realistic Operating Cycles

Increasing demands in terms of reducing the cost of running forestry machines along with the regulatory pressures for lower exhaust emissions encourages the usage of hybrid powertrains in field applications. Hybrid power-trains consist of two or more different energy sources, which leads to many open questions in terms of energy management control, which have significant influence on the power-train, efficiency, fuel consumption and consequently on the operating cost and emissions of greenhouse gasses. Therefore, this paper proposes the optimal energy management control strategy intended to be used in hybridized articulated forestry tractor, also known as skidder. The proposed control strategy is verified on the previously developed skidder model by a comprehensive simulations over realistically recorded field data. The simulation results are used to gain insights about the possible advantages of proposed optimal control strategy in terms of feasible reduction of fuel consumption and related CO2 emissions.
