Characterization of MSMA-based Pneumatic Valves
The deformation range, forces and frequency of the Magnetic Shape Memory Alloys (MSMAs) render them suitable for applications in electro-mechanical transducers, used to control pneumatic valves. A fast-operating electro-mechanical transducers can be designed, whose driving elements should not execute any motion, as they do in valves available to date, and which should get deformed instead. Util...
متن کاملControl of a joint actuated by two Pneumatic Artificial Muscles with fast switching ON-OFF Valves
The power to weight ratio of the actuators is an important design factor for running robots. In this regard pleated pneumatic artificial muscles are excellent actuators. Another advantage is that they can actuate a joint directly, avoiding the additional weight and cost of a gearbox. Obviously the weight of the pressure control valves has to be taken into consideration as well. For this applica...
متن کاملPneumatic pulse-width modulated pressure control via trajectory optimized fast-switching electromagnetic valves
The design of a pneumatic pulse-width modulated pressure control via trajectory optimized fast-switching electromagnetic valves is presented. Two fast-switching valves are used in a half bridge configuration for pressure control in a pneumatic volume. The valves are operated using a feedforward control, which guarantees soft landing and time optimality. The control performance and achievable no...
متن کاملSliding Mode Approach to PWM-Controlled Pneumatic Systems
This work presents a modeling and control design method for PWM-controlled pneumatic systems. Difficulties associated with servovalves typically used to continuously control pneumatic systems, in addition to a general lack of analytic control design techniques available for PWMcontrolled pneumatic systems, motivate the development> of a modeling and control design technique for PWM pneumatics. ...
متن کاملSTABILITY OF PNEUMATIC and HYDRAULIC VALVES
There are three forces acting on the valve plate: the force of the escaping air Fv, the force of the steel spring Fs and the pneumatic damping force due to the pressure of the air in the dashpot Fd. Each of these forces varies with distance x. These interact with the valve mass and the pipeline dynamics to produce instability. Perturbations in the pressure travel along the pipe at the sonic vel...
