Precision Position Tracking of Mr-compatible Pneumatic Piston-cylinder Using Sliding Mode Control
This paper presents the nonlinear dynamics and sliding mode control design for a 1-DOF needle insertion robot. The robot actuator is an MR-compatible pneumatic piston-cylinder. A brief review of the dynamics for this type of actuator is provided. The reaction force of tissue on the needle remains an unknown for which our controller compensates. A sliding mode control law is formulated that reli...
متن کاملPrecise Control of the Piston Position and the Pressure of Cylinder Chambers for the Pneumatically Actuated Leg
In the pneumatically actuated leg control system, precise control of the piston position and the pressure of cylinder chambers is a tricky problem. In this paper, a new control scheme is introduced, in which the gas internal energy of the cylinder’s two chambers is used as the set point for PD controller. The proposed control scheme is essential to control the piston position and the chamber pr...
متن کاملEffect of time-dependent piston velocity program on vortex ring formation in a piston/cylinder arrangement
An analytical model describing laminar vortex ring formation in a nozzle flow generator piston/ cylinder arrangement proposed previously by the authors is extended to time-dependent velocity programs. The predictions of the model are in good agreement with the available numerical data for impulsive, linear, and trapezoidal velocity programs. We also show that properly scaled vortex circulation ...
متن کاملDevelopment of a Two-Cylinder Rolling Piston CO2 Expander
Carbon dioxide (CO2) as a natural refrigerant is one candidate alternative to HFC refrigerants. But CO2 system has lower efficiency and is not yet competitive concerning the COP. The most effective method to improve the efficiency of the transcritical CO2 system is to replace the throttling device with an expander. In this paper, a two-cylinder rolling piston expander without inlet valve has be...
متن کاملDiss . ETH No . 19386 INDIVIDUAL CYLINDER AIR - FUEL RATIO CONTROL
The thesis presents a complete framework for the design of an individual cylinder air-fuel ratio (A/F) controller that aims to further reduce the exhaust emissions of modern automotive gasoline engines. It is well known that this type of controller relies on a correct estimation of the A/F of the individual cylinders. Otherwise, the control system can become unstable. Therefore, the conditions ...
