Multivariable Adaptive Flight Control system for fixed-wing UAVs

The programs above are in three Matlab .m files, i.e.

• simulate_algorithm.m
• adaptive_algorithm.m
• simu_plot.m
  
  ⚠️ Save the A and B matrix of the UAV in data.mat as A_LONG and B_LONG respectively.
  
  In the Matlab environment, type the following command at the command window.

simulate_algorithm

The function ode45 in simulate_algorithm.m calls the function adaptive_algorithm for each time step.

The data generated by the programs is saved in the file simulation_data.mat as the numerical solution to those differential equations to describe the dynamic system.

Use simu_plot to plot the results of simulation. The simulation results are showed in the following figures.
