Optimisation of the dynamic response of gimbal seeker plays key role from the point of view of development of anti-tank guided missile’s systems. In this study the set of the most important internal disturbances were integrated in generalized model of two axis gimbal seeker implemented in MathWorks’ Simulink environment. Compared to previous works on the subject, it was enhanced by replacing simple friction model with dynamic LuGre friction. Furthermore, its Coulomb component was linked to the normal force induced by missile’s lateral acceleration. Control system of gimbal seeker proposed in paper was tuned with modelled disturbances turned off and then examined with them being turned one by one. System’s responses were assessed to be significantly deteriorated, proving need of disturbance modelling and its use in control systems’ design.
