“…Nguyen separated the controller into two control loops related to mechanical and hydraulic dynamics, which allowed them to reduce the controller's order and increase its robustness. Similarly, Li et al [25] analysed an adaptive fuzzy controller for an electro-hydraulic servo system. Moreover, Truong et al [26] designed a back-stepping sliding mode fuzzy logic system, including two controllers for a manipulator and an actuator, respectively.…”

“…The first possibility is a standalone fuzzy controller generating the output signal based on the control error and its derivative. This attempt was made by Nazari and Surgenor [77], Li et al [25], Khaziew et al [78] as well as Šitum and Ćorić [79]. It is worth emphasizing that Šitum and Ćorić used an innovative inference method in their system.…”

Fuzzy logic has been developed since the 1960s. Research related to fuzzy logic application in hydraulics and pneumatics is mainly aimed at energy demand reduction and improvement in operational characteristics. This article summarizes the recent achievements in hydraulic and pneumatic fuzzy logic system design. First, the main application areas have been identified, including control and fault diagnosis. The control systems were additionally grouped according to the main objects of study, such as pumps, actuators, proportional valves, etc. Then, the results of the recent research were presented, and the main features of the designed fuzzy logic units were summarized for each group. Particular attention was paid to types of membership functions used for fuzzification and defuzzification, numbers of fuzzy sets defined for input and output signals, types of fuzzy operators, the applied inference algorithm and the defuzzification method. Based on the analysis of the listed parameters, conclusions were formulated regarding advantages, main issues and difficulties, as well as recommended directions for further development.

“…To circumvent the filtering error, the command filtered backstepping (CFB) was developed via the error compensation mechanism (see [6]- [9]). The work [6] initially discussed the impact of the command filter for the system stability, and then, this team presented an adaptive BC for the land vehicles [7].…”

“…Due to the serious harm caused by discharge faults, the detection of dissolved C 2 H 2 is particularly important. According to the IEEE guide, the alarm value of the online monitoring device of substation equipment for C 2 H 2 gas should reach 1 μL/L 6,7 . Therefore, the highly sensitive detection of dissolved C 2 H 2 has great significance for very early failure warning of transformers.…”

Aiming at the need of rapid and sensitive detection of acetylene dissolved in oil, a small‐volume T‐type photoacoustic (PA) cell was proposed. By optimizing the design parameters, the volume of the T‐type cell was reduced to 30 mL, which resulted in a significant reduction in the sampling amount of the transformer oil. A laser PA spectroscopy system for dissolved gas analysis was built combined with the headspace degassing method. A near‐infrared tunable laser with wavelength modulation spectroscopy was employed to detect the escaped acetylene gas from oil. Test results show that the detection limit of dissolved acetylene reaches 0.2 μL/L when the sampled oil volume is 50 mL. In addition, the degassing balance time can be shortened to 270 s. This scheme has the superiority of small oil extraction volume, high accuracy, and short response time, providing a new method for analyzing the dissolved characteristic gases in oil.
