...Khurram Butt; Nariman Sepehri A force-controlled pneumatic actuator with long connecting tubes is a well-accepted solution to develop magnetic resonance imaging (MRI)-compatible force control applications. Such an actuator represents an uncertain, second-order, nonlinear system with input delay...

...Karim Khayati; Pascal Bigras; Louis-A. Dessaint The purpose of this paper is to develop an accurate closed-loop acting force technique for a pneumatic actuator, as an essential stage in the implementation of positioning control strategy. Since an analytical nonlinear structure, which linearly...
