Recent Trends

There are many machines that require human operation in industry, and high operational skills are required to operate these machines efficiently. However, the number of highly skilled workers is decreasing due to the recent trends of falling birthrate and population aging. This decline is particularly pronounced in the construction industry, while the demand for construction workers remains high owing to the increasing number of developed infrastructures. To reduce this mismatch between the supply and the demand, it is important to achieve high efficiency in tasks using hydraulic excavators, because these machines can greatly increase the productivity at construction sites. Accordingly, it is necessary to improve productivity even if unskilled operators use hydraulic excavators. This paper proposes a control system that achieves efficient motions based on the velocity of the center of mass (CoM) of the hydraulic excavator’s attachments, which reflects the characteristics of skilled workers’ operations. The motions of multiple attachments give rise to interference terms owing to the characteristics of the hydraulic system. A two-input two-output control system, in which the input consists of the lever input and the output is the CoM velocity is constructed. The fictitious reference iterative tuning (FRIT) method is used to calculate the controller parameters. The proposed method was verified by comparing the results of a simulated digging motion and an experiment with an actual hydraulic excavator operated by an unskilled operator.

Electro-hydraulic systems (EHS) are widely used in industrial applications due to the high-power density and accuracy. However, EHS are highly nonlinear which makes its modelling and control aspects a complex process. In this paper, we present the modelling and position control for an electro-hydraulic system (EHS). The mathematical modelling is carried out considering the non-linearities like friction, discharge coefficient and load mass present in the system. A back-stepping control scheme is developed for maintaining the accuracy in the position control. The closed-loop stability of the proposed control system is analyzed with Lyapunov’s theory. The performance of the control system under the effect of bounded external uncertainties is validated with simulation study. The study indicates that the proposed controller gives an effective motion control in presence of the system uncertainties.
