The aim of the study was to perform bioelectric signal analysis focusing on its applicability to control of the electro-hydraulic servo drive. The natural bioelectric signals generated by brain, facial muscles and eye muscles read by the NIA (Neural Impulse Actuator) are translated into control commands in the controller of electro-hydraulic servo drive. Bioelectric signals detected by means of special forehead band with three sensors are sent to the actuator box, where they are interpreted as control signals.

Abstract:
In this paper, a new solution for an electro-hydraulic servo drive is proposed, which consists of two electro-hydraulic servo drives: one with a hydraulic cylinder and one with a hydraulic rotary motor. In the proposed drive, the linear actuator is attached to a horizontal base and the hydraulic motor is mounted on the actuator piston rod. Thus, the output signal of the drive is the lifting and lowering of the element suspended on the rope.

Abstract This paper presents the modelling and simulation of a servo electro-pneumatic actuator utilizing solenoids. Many control actuation systems employ electro-hydraulic or electro-mechanical servo actuators. However, electro-pneumatic servo actuators using solenoids are becoming more popular due to their lower cost and simpler structure. Pneumatic actuators are preferred due to their low cost, simple structure, fast response, low electromagnetic interference, high force/weight ratio.

However, as these systems are optimized, and their dimensions are reduced, the thermal effects of fluid flow become more relevant.

Electro-Hydraulic Systems (EHS) are commonly used in many industrial applications.

Current practice to detect faults in the actuators can miss failures with combination of multiple sources. Missed faults can result in sudden, unforeseen failures. We propose a fault detection technique based on Multiple Regressor Adaptive Observers (MRAO). The results were evaluated using a two-stage servo-valve model.
