An easily implemented adaption technique was derived analytically for the synthesis of model-referenced adaptive control systems. The simplicity of this technique gives it a distinct advantage over other techniques that have been described in the literature and makes it attractive for practical applications. The direct approach to the problem employs the state-space point of view. Solving the differential equations of the reference model and the adaptive control system leads to an expression showing the explicit functional dependence of the performance error on the adaptive parameters. Manipulation of the expression for performance error yields the adaption equations, which are very simple to implement. Model-referenced adaptive control systems utilizing this simplified adaption technique are investigated by means of an extensive stability analysis. Computer simulations are made to verify the various theoretical results obtained and to give some indication as to the performance capabilities of the simplified adaption technique. The model-referenced approach is shown to have application in the design of high-performance aircraft and missiles.
