Multicriteria fuzzy-polynomial observer design for a 3DoF nonlinear electromechanical platform

Abstract: This paper proposes local fuzzy-polynomial observer discrete-time designs for state estimation of a nonlinear 3 DoF electromechanical platform (fixed quadrotor). A trade-off between H ∞ norm bounds and speed of convergence performance is taken into account in the design process. Actual experimental data are used to compare performance of the fuzzy polynomial design with classical ones based on the Takagi-Sugeno and linearized models, both using the same optimization criteria and design parameters.

“…In this case, a trade-off between H ∞ norm bounds and speed of convergence performance is taken into account in the design process: H ∞ is a worst-case measure (of disturbance/model error rejection) so its solutions are conservative in practice whereas decay-rate optimization produces unacceptable noisy estimates. The theoretical results presented in this section have been used for the experimental applications (Part III of the thesis) and appear published in the journal paper Pitarch and Sala (2014). Both continuous-time and discrete-time design methodologies can be pursued in order to obtain an observer with the objective of achieving acceptable behaviour in practice.…”
