The problem is presented of controlling a stable, slowly time varying, linear process. A solution is proposed that is simple, practical and applicable to any finite order process. Use is made of a continuously adjusted tandem compensator a comparison of the weighted histories of the input and output signals is used to control this adjustment. System design is based upon the use of a variable transfer function characterization for both the compensator and the process. In effect, a compensator is designed that attempts to cancel the variable poles of the process with variable zeros, the variable zeros of the process with variable poles and the variable process gain with its reciprocal. The design technique developed is applied to several problems. The processes involved range from a variable gain amplifier through a plant that contains a variable gain and two pair of variable complex poles. The processes are grouped in accordance with the number of variable parameters in the process characterizing function.
