Adaptive Time Varying Autopilot Design
Nataša Vlahović Stevica Graovac Miloš Pavić Milan Ignjatovi
Missile autopilots represent devices for precise following of a target that missiles are sent to intercept. Commands that need to be executed are forwarded to the autopilot in order to achieve demanded performance. Usually, in representation of an autopilot and its performance, a model with constant parameters is used. Constant autopilot parameters and missile coefficients are calculated from time varying values. Model with constant parameters is shown in this paper, as well as the results obtained from this model. These values are then used as the initial ones for calculations in time varying pitch autopilot model design based on gain-scheduling. It is shown how the coupling with other axis such as yaw is cancelled by using time varying parameters. All the models are implemented in Matlab and Simulink toolbox.
Key words: autopilot, design, adaptive device, adaptive control, pitch, time varying parameters, coupling.
