Parameter estimation of aircraft using extreme learning machine and Gauss-Newton algorithm

Abstract: The research paper addresses the problem of estimating aerodynamic parameters using a Gauss-Newton-based optimisation method. The process of the optimisation method lies on the principle of minimising the residual error between the measured and simulated responses of the system. Usually, the simulated response is obtained by integrating the dynamic equations of the system, which is found to be susceptible to the initial values, and the integration method. With the advent of the feedforward neural network, the … Show more

“…Once the network trained, the aerodynamic coefficients C Y , C l ,C n in the network input are replaced by the estimated values ĈY ; Ĉl ; Ĉn of the aerodynamic coefficient model (31), and then the output of the network is obtained. Furthermore, LM algorithm based on PSO is used to estimate the parameter vector H. For the three kinds of networks, the initial guess of H can be selected randomly, which is different from the constraint of parameter selection in the vicinity of EEM estimation results proposed by Verma and Peyada (2020) . The estimates of parameter vector H based on EEM, FEM and NN-LM are shown in Table 4.…”

“…Extreme learning machine (ELM) was used to substitute for the traditional FFNN in the nonlinear modeling of the aircraft’s dynamic model owing to its robustness and noniterative training way, and GN algorithm combined with ELM was used to estimate aerodynamic parameters of stable and unstable aircraft (Verma and Peyada, 2017, 2018, 2020). Although these researches focused on the improvement of neural network, all of them used GN algorithm in the process of parameter estimation.…”

“…Two major techniques that have been widely used and well developed are the time-domain identification and the frequency-domain identification (10) . The Maximum Likelihood (ML) method is by far the most commonly used time-domain technique for estimating parameters from dynamic flight data (14,(16)(17)(18) . Previously, Saderla et al (12,17) efficiently applied the ML together with Gauss Newton (GN) method to estimate longitudinal and lateral-directional parameter for Unmanned Aerial Vehicle (UAV).…”
