摘要: In this study, the authors address non-linear tracking problem of a roll-rate-sensorless vertical take-off and landing aircraft in presence roll-angle measurement delay. By using first-order Pade approximation signal delayed roll angle, develop an extended attitude observer controller based on observer, two global coordinate transformations extension backstepping technique. Moreover, finite-time-convergent differentiator is introduced to simplify computation one control signals. The resulting approximate practicable for actual implementation. Numerical simulations are performed show effectiveness controller.
