A method constructing vacuum servo control system with a combined vacuum generator is proposed and the single neural adaptive PID control strategy is also proposed due to the inherent defects of the vacuum servo system in this paper. The influence of the system parameters to the characteristics of the vacuum servo system is analyzed and discussed. The simulation and the experiment show that the...

A method based on binocular vision servoing for positioning of a diagnostic package in inertial confinement fusion (ICF) experiments is presented. The general diagnostic instrument manipulator will provide precision three dimension positioning and alignment-to-target capability in ICF experiments. In this work, we focus on the final precise automatic positioning with a binocular vision system. ...

The article presents the problem of synchronization piston rods velocity multi-cylinder electro-hydraulic servo drive. This task was presented on example a heavily loaded mobile caterpillar platform. For levelling platform, four-post support mechanism with proportional valve control system used. A linear external controller to synchronize movement cylinders used and non-linear internal for each...

This study aims to develop a complex hybrid 3D robot with parallel links driven by the nonlinear pneumatic servo system for path tracking control. The mechanical system and the control system are the primary parts for developing a complex hybrid 3D robot. In the mechanical system, a complex hybrid 3D robot contains serial manipulators, parallel links, base plates, a movable platform and a pneum...

This on-treatment analysis was conducted to facilitate understanding of mechanisms underlying the increased risk of all-cause and cardiovascular mortality in heart failure patients with reduced ejection fraction and predominant central sleep apnoea randomised to adaptive servo ventilation versus the control group in the SERVE-HF trial.Time-dependent on-treatment analyses were conducted (unadjus...

This chapter introduces visual servo control, using computer vision data in the servo loop to control the motion of a robot. We first describe the basic techniques that are by now well established in the field. We give a general overview of the formulation of the visual servo control problem, and describe the two archetypal visual servo control schemes: image-based and position-based visual ser...

The positioning accuracy achievable by track-follow servo for flexible tape media is investigated using advanced concepts for several elements of the system. First, the servo pattern geometry in the timing-based servo system is designed in conjunction with a digital synchronous servo channel to minimize the measurement error in the position-error signal. Second, a flangeless tape path is introd...

In this paper, the main transmission mechanism of double servo drive symmetrical toggle press was taken as object study. The theoretical derivation its motion characteristics carried out. A parametric model established to analyze rigid body kinematics. kinematic performance improved by rigid-flexible coupling. research results could provide an important reference for development large-tonnage w...

In the paper, a fuzzy variable structure control with a harmonizing mechanism has been developed and applied to the positioning control of an electro-hydraulic servo system. The simulation experiment results show that the performance by using the controller is better than those by just only using either fuzzy controller or variable structure controller. In addition, it also demonstrates that it...

controller structure is made by taking a traditional servo mechanism based on Linear Quadratic approach and by augmenting a new state variable to the feed forward loop. Since the controller structure is consists of a standard optimal feedback regulator and a feed forward controller, it is able to enhance the usefulness of resources and to reduce unnecessary memory reservations such as RAM (Rand...
