Summary: | This article demonstrates the application of a recently proposed sliding mode observer concept for linear time-invariant multivariable systems with unknown inputs. In contrast to other sliding mode approaches, this observer concept does neither unnecessarily increase the observer order beyond the plant order nor requires bounded state variables or some restrictive relative degree conditions. This work aims for estimating the temperature profile along an aluminium rod, which is excited with heat fluxes unknown to the observer. The plant model is transformed into a suitable form for observer design, facilitating a straightforward sliding mode observer design. Experimentally obtained estimation results confirm the effectiveness of the observer in a practical application. |
