Control valve is a tool in the oil and gas industry that works by relying on actuators as driving force. For example, pneumatic work with air pressure energy, standard signals are used for pneumatic. The signal converted into current using fuzzy an application of artificial intelligence systems industrial sector. method this study utilization logic Mamdani software MATLAB. results will be compa...

To achieve more accurate tracking control, a control strategy for servo pneumatic systems based on the feedback linearization theory is presented. The nonlinear pneumatic actuator system is transformed into a linear system description, with a linear input–output map by regular static state feedback and state coordinate transformation. A servo tracking controller is then developed for the system...

This dissertation reports on the developments of the bipedal walking robot Lucy. Special about it is that the biped is not actuated with the classical electrical drives but with pleated pneumatic artificial muscles. In an antagonistic setup of such muscles both the torque and the compliance are controllable. From human walking there is evidence that compliance plays an important role in energy ...

Air brake system has been widely used in heavy trucks and intercity buses for its great superiority over other brake system. The practical performance of air brake system may be greatly different from if we analyze it with static theory. Thus, it is necessary to build an integrate air brake system model to simulate the process of brake accurately. However, the dynamic mathematic model of air br...

A control valve is the most heavy and expensive device in pneumatic driving system for a soft mechanism. To realize compact inexpensive system, size, weight, cost of must be reduced. In previous study, small-sized servo that can flow rate using diaphragm gate mechanism, driven by low-cost RC motor, was proposed tested. However, mechanism should adjust relative positions rotating disk to achieve...

This paper presents an approach to design a nonlinear controller for a pneumatic cylinder system for which the connection port comprises a non-negligible restriction. The pressure chamber of this system is difficult to control because the servo valve and the connection port form a double restriction. This double restriction causes a singularity in the feedback linearization controller. To avoid...
