โœฆ Synopsis

This paper presents a low-order controller design method, using closed-loop modelling plus covariance control, with application to the benchmark problem in structural control for the active mass drive system at the University of Notre Dame (see Reference 1). This method finds a satisfactory controller by iterating between the closed-loop modelling and the covariance control. The closed-loop modelling implies that the model used for model-based control design is extracted from the feedback system of the last iteration. The covariance control finds the optimal controller to minimize an output variance and at the same time to bound the other output variances.

The standard configuration for model-based control design is reformulated into a twin feedback configuration with the model and controller written in separate feedback loops. Closed-loop balanced reduction is developed in this framework. A scheme with alternating model reduction, optimal control syn
