“…In the simulation, we assume the saturation limit in the external yaw moment is 4.0 kNm [39]. To verify the advantage of the modified CNF technique, we have compared it with the LQR technique, which is a commonly used optimal control strategy due to its superiority in yielding low steady-state error with fast response [40]. The controller gains in the reference yaw rate generation for both of the two cases are: k 1 = 3/v x , k 2 = 30k 1 .…”

“…Another common approach is the Linear Quadratic Regulator (LQR) for attitude stabilization [23][24][25]. While this may be applicable for some configurations, multirotors are non-linear systems that present uncertainties, such as unknown physical parameters, actuator degradation, unknown delays in-process communication and unmodeled dynamics [26].…”

“…Theorem 1. Considering the system defined by (6) and the estimator model (9) by using a EKF adjustment law defined by (14). The neural observer based on EKF is semiglobal uniformly ultimate bounded (SGUUB) and it is stable.…”

“…[9][10][11] Other studies proposed the UAV control based on PID controllers with artificial intelligence and dynamic properties, such as the controllers presented in the work of Yang et al, 12 where authors defined a single-neuron PID, where the adjusting of the weights is a function of the control errors. However, since quadrotor is a nonlinear underactuated systems, 8 it is not always possible to use PID control directly for the quadrotor system.…”
