Special Issue Information

Dear Colleagues,

Currently, the consumption of electric energy input is required to be more efficient for the same performance in driving a mechatronics system.  Therefore, energy-saving motion control has gradually attracted more attention from scholars.

In this Special Issue, we invite contributions regarding energy-saving trajectory design, control, and novel technologies for academic and industrial applications. Studies with numerical simulations and experimental results are all encouraged to be published in the Special Issue.  Using artificially intelligent algorithms, energy-saving trajectory design may be accomplished. Using the nonlinear tracking control, it is possible to achieve the minimum input electrical energy, and the new technology can be implemented in real-world industrial applications. Those who wish to contribute articles related to the above energy-saving techniques are welcome to submit them to this Special Issue.

Nowadays, hydraulic excavators are an indispensable part of the construction industry; however, conventional hydraulic excavators consume a great deal of fossil fuel and release a large amount of pollution emissions into the environment. This causes many unwanted costs, therefore, effective solutions are required to solve the above-mentioned problems. In this paper, a new independent metering system is proposed to improve energy-saving and reduce costs of a conventional system. In detail, a directional valve is used to control movement and three electro-hydraulic poppet valves are integrated to adjust the flow rate at the inlet and outlet ports of the boom cylinder. In addition, a control strategy based on the coordination between the speed of the pump and the opening area of the spool valve is designed to improve the performance of the system. Specifically, the valves are controlled based on the strategy that the meter-in valve is opened fully to reduce throttling losses and that the meter-out valve is controlled to reduce leakage. The speed of the pump is adjusted according to the feedback position signal. To demonstrate the effectiveness of the new configuration, a real test bench of the boom system was built under laboratory conditions. From the experimental results, the new independent metering valve system not only works with a high tracking precision, but it also reduces energy consumption. Compared with a conventional independent metering system, the fuel economy of the proposed structure can achieve a reduction of approximately 6.5%. Full article
