Variable Structure Robust state Observer design for a Pneumatic Artificial Muscle actuator

The Variable Structure Robust state Observer (VSRO) design for Pneumatic Artificial Muscle (PAM) actuator are proposed. The observability matrix of the nominal nonextended system shows the observation of state variables. Simulation results shows the designed VSRO provides good performance of observation. The experiment results will be show in full paper.
