The objective of the work, is the design of a non-square multivariable control system, and the development of programs to analyze the internal loop stability. To do this, an airplane automatic pilot system is used, whose non-square multivariable model was supplied by the Department of Aerospace Engineering of the Delft University of Technology. The methods to be used in the project will be the 'Extended Inverse Nyquist Array' and the 'Sequential Loop Closure'. The first method will be used in the closure of the internal loops, while the second one, on the closure of the external loops. Two automatic calculation programs to analyze the loop stability will be presented; the first a Routh-Hurwitz method based program and the second based on the Root-Locus method. If the results of the design prove of good quality, they are to be implemented on the flight simulator of the Delft U.T., after being generalized for all flight conditions.
