Bibliographic Details
Summary:With the use of matrix inequalities, this work proposes a gain as a function of the control variables, that is able to guarantee the stability of the model and reduce the disturbances regardless of the condition in which the aircraft is involved. A study is performed around the linearized equilibrium conditions for a Lynx ZD559 model. In this, the independent control variable is the forward speed of the aircraft. The results obtained from a stationary controller, one with commutable variation and one of linear variation elucidate the ability of the last controller to operate over the entire spectrum of speed variation by presenting an acceptable transient dynamics and disturbance rejection.
