Abstract :
A mixed sensitivity H∞ control methodology is tested on a three-tank-system laboratory prototype. The methodology is based on a stable precompensator and its dual post-compensator which allows to solve a mixed sensitivity problem. Frequency responses show that it is possible to shape the open loop transfer function by the control parameters. Time responses are given under flow leak, close connection valve and sensor failure.
