“…In many fuzzy control systems, the fuzzy rule base depends on control error e and control error rate e that complicate the fuzzy inference rules and the membership functions. In order to reduce the fuzzy rules in fuzzy controller, fuzzy sliding mode controllers (FSMC) that combine fuzzy control theory with sliding mode control were quite developed [15][16][17]. In this paper, signed-distance fuzzy sliding mode control (SD-FSMC) [18] is used to design the hydraulic servo controller.…”

Electro-Hydraulic pump-controlled servo systems that have high energy-efficiency can serve as energy-saving system. This paper aims to investigate the servo performance of the electro-hydraulic pump-controlled systems driven by an AC servo motor with variable rotational speed. A constant displacement axial piston pump is used in this research. Thus, the new hydraulic pump-controlled system with an AC motor servo and a constant displacement axial piston pump is investigated for position control of hydraulic servo machines. For that, this paper also develops the control strategy, sign-distance fuzzy sliding mode control, which can simplify the fuzzy rule base through the sliding surface. The developed high response variable rotational speed pump-controlled systems controlled by SD-FSMC are implemented and verified experimentally for positioning control in different stroke and loading conditions.

“…B. Lashgari used fuzzy classification theory in 1989 to analyze geophysical data. The application of Fuzzy Logic was motivated by how inaccurate or unreliable geophysical data can become and by the inconsistencies generated in the results when applying Bayesian classifiers (Tzafestas & Rigatos, 1999). Fuzzy logic control has also been employed in automatic drug administration systems.…”

A high servo control response and a high energy efficiency, which are difficult to achieve simultaneously, are requested in hydraulic servo systems of current hydraulic injection moulding machines. This investigation develops new solutions to concurrently implement energy-saving control and velocity control for simultaneously realising high velocity control response and high energy efficiency for injection moulding machines. Two different hydraulic pump systems, including a variable displacement pump and a variable rotational speed pump, are developed and in each one of them two different energy-saving control concepts, such as load-sensing control and constant supply pressure control, are implemented. Thus, for verifying the feasibility of the integrated control systems and comparing the energy-saving effects, velocity control of the hydraulic cylinder can be integrated with four different energy-saving control systems (ESCSs) and also the conventional hydraulic system without energysaving control. A fuzzy sliding mode control that can simplify the complex fuzzy rule bases is used for solving the complex two-input two-output systems. The experimental results show the excellent performance of the integrated concurrent control systems.
