Application of Optimal Tracking Methods to Aircraft Terrain Following
Abstract
Some approaches using least squares optimization for improving tracking control system performance are developed and applied to a simplified aircraft terrain following problem. A basic tracking control system is described. The design of an optimal moving-average precompensator which gives improved tracking performance over the basic system is then given. This filter design is modified to use future values of the reference input to give further improved performance. An approach involving the design of an optimal signal to drive the control system is also given. These approaches are applied to an aircraft terrain following system simulation. The performance obtained is examined and discussed. It appears that as worthwhile performance improvements can be obtained by using the algorithms which make use of knowledge of future terrain as could be obtained from a terrain data-base. These improvements allow the aircraft to fly at lower altitudes. Keywords: Air navigation. Australia.
