Level control of liquids in coupled tanks is a basic requirement in many
industrial processes. Liquid levels in tanks must be controlled accurately
regardless of environmental circumstances. Minor faults in sensors, actuators
or other system components that take place in processes where liquid level
control is required can result in catastrophic consequences. In this case, a
fault tolerant control system is needed. The controller must be either robust
(passive) or in reconfigurable (active) type in order to compensate for the
effect of actuator faults and maintain system reliability and performance. In
this study, a water tank level control system and possible valve actuator
faults are modelled. By designing different controllers and using modelled
failures a simulation is constructed. To test the reconfigurable type
controller performance against faults/failures, a model reference adaptive
control system is implemented and compared with PI-controlled system.
