A CAD Method and Associated Architectures for Linear Controllers,

Abstract

New architectures and an associated CAD method are proposed for linear controllers. The architecture is suggested by recent results which parameterize all controllers that stabilize a given plant. With this architecture the design of controllers is a convex programming problem which can be solved numerically even for large systems. Constraints on the closed-loop system such as asymptotic tracking, decoupling, limits on peak excursions of variables, step response settling time and overshoot, as well as frequency domain inequalities of any H infinity variety are readily incorporated in the design. The minimization objective is general and can include LQG, H infinity, new l sub 1 types, or any combination thereof. To specify the constraints and objectives mentioned above, we are developing a control specification language. (Author)
