With respect to similar software packages, APRICOT is customizable in all its aspects, and has been released as open source software. Hence, the proposed toolbox has applicability both for educational purposes and control rapid prototyping. The main goal of APRICOT is to provide a simulation environment to test and validate different control laws with different aircraft models. Moreover, different aircraft models can be easily integrated. All details of the dynamics can be easily customized in the toolbox, some examples are shown in the paper. The toolbox, named APRICOT, is able to simulate the longitudinal and laterodirectional dynamics of an aircraft separately, as well as the complete 6 degrees of freedom dynamics. The discrepancy between the simulation and flight test response showed significant improvement, which satisfies the regulation tolerance.Ī novel MATLAB/Simulink based modeling and simulation environment for the design and rapid prototyping of state-of-the-art aircraft control systems is proposed. The presented results demonstrate that the applied enhancement procedure has improved the simulation accuracy in longitudinal motion.
A simulation validation process is introduced to evaluate the accuracy of the enhanced 6 DOF simulation model. Next, the classical Maximum Likelihood (ML) estimation method is applied to calculate aerodynamic derivatives from flight test data, these parameters are utilised to correct the initial aerodynamic table. The enhancement process starts with identifying longitudinal equations of motion for sensitivity analysis, where the effect of crucial parameters is analysed and then adjusted using the model tuning technique. The baseline simulation model database is constructed using multi-fidelity analysis methods such as wind tunnel (W/T) test, computational fluid dynamic (CFD) and empirical calculation. In this study, the full-scale flight testing of a 2-seater aircraft has been performed in specific longitudinal manoeuver for model enhancement and simulation validation purposes. This paper proposes a procedure to improve the accuracy of the light aircraft 6 DOF simulation model by implementing model tuning and aerodynamic database correction using flight test data.
The developed virtual lab can be used easily by students to study and visualize classical control principles using FlightGear and MATLAB GUI with an attractive case study of a flight control system. These concepts are demonstrated in four experiments through the analysis and design of a flight control system for Cessna 310 aircraft on FlightGear flight simulator.

This objective is achieved through a series of experiments, animation and simulation to illustrate main concepts of classical control like modeling, time domain analysis, frequency domain Analysis, non-minimum phase systems, root locus, feedback design and PID compensation. Implement a hold autopilot for the aircraft. The objective of the virtual lab is to design a stability augmentation system for C310 aircraft model according to known flying qualities then The virtual lab consists of number of experiments that enhances the understanding of fundamental concepts of classical control for undergraduate students. In this paper, a virtual lab based on MATLAB and FlightGear flight simulator is discussed and developed.
