“…On the other hand, the PBW actuation system has high reliability on account that it uses flexible cables for power transmission and gets rid of the central hydraulic power, such as EHA. This has been one of the major development directions of PBW, which have been introduced by different researchers in [6][7][8][9][10]. Besides, EHA produce high force with a cleaner and more energy efficient way [11].…”

“…1). In recent years, there has been a large body of research devoted to the dynamics and control of systems with a hydraulic motor [16][17][18][19][20]. All these studies are characterized by a unified approach, which consists in formation and numerical modeling taking into account specific features of the mechanical (drive) system.…”

Mathematical models describing technically oriented dynamical systems are generally rather complex. Very time-consuming interactive procedures have to be used when selecting the structure and parameters of the system. Direct enumeration of options using such procedures can be avoided by applying a number of means, in particular, dimension methods and similarity theory. The use of dimension and similarity theory along with the general qualitative analysis of the system can serve as an effective theoretical research method. At the same time, these theories are simple. Using dimension and similarity theory, it is possible to draw conclusions when considering phenomena that depend on a large number of parameters, but so that some of them become insignificant in certain cases. The combined method of using the theory of similarity, analogousness and methods developed by the authors for testing the drive model provides insight into its dynamics, controllability and other properties. The proposed approach is based on systematization and optimization

“…Lemma 1 indicates that for arbitrary small approximation error bound ε > 0 of the unknown continuous nonlinear function f 2 (x 2 ) in the VP-EHS (7), there must exist suitable ideal parameters of the FLS (12). It should be noted that if the number of the rules k is fixed, the approximation error cannot be made arbitrarily small only by tuning the width and center of the membership function (9), and the quantization range of the quantization function (10). Increasing k is helpful in decreasing the approximation error [40,41].…”

This paper presents a novel adaptive composite fuzzy dynamic surface controller for a variable-supply-pressure electro-hydraulic-system in the presence of unknown nonlinear friction effects. To avoid analytic calculation, command filters are utilized to produce certain virtual controllers and their derivatives. A fuzzy logic system is designed to approximate and compensate the unknown nonlinear friction influences of the electro-hydraulic-system. To achieve a precise approximation, the prediction error of a designed serial-parallel estimation model and the compensated tracking error are both used to develop the composite adaptive law. Comparative simulation and experimental results are obtained to verify the effectiveness of the proposed control method.
