Abstract: This paper presents an experimental evaluation of three different kinds of real-time state observers for twin rotor multiple-input-multiple-output (MIMO) system. The twin rotor MIMO system (TRMS) exemplifies a high order non-linear system with significant cross couplings. Based on the experimental results a comparative analysis of Chebyshev neural network-based observer and sliding mode observer with local state observer is presented. Finally, the robustness issues are also addressed.

Keywords: twin rotor MIMO systems; TRMS; nonlinear systems; local state observers; Chebyshev neural network observer; sliding mode observers; neural networks; multiple-input-multiple-output systems; cross couplings; sliding mode control; SMC.
