When a controlled system is subject to external disturbances of large magnitude, the regulator often uses a mixed strategy, combining a feedforward link to neutralize the primary impact of the disturbance, and a feedback link to reduce the effect of any residual. If there is a possibility of error in measuring the disturbance, the problem becomes more complex. A sophisticated regulator might even try to “learn” the true value of the disturbance. Attempts to design such an intelligent regulator usually lead to intractable synthesis equations. This paper provides a simple alternative for the case in which the measurement of the disturbance is close to the true value. A study of a simple model of a solar-powered boiler shows that the performance of the proposed regulator is near that attainable by much more complicated controllers.
