Generalized singular robust control design

A generalized singular robust control approach for missile autopilot design is described. This approach unifies the generalized singular linear quadratic linear quadratic Gaussian, and worst-case H^∞ control design methods using the generalized Hamiltonian formulation and structure algorithm. Extensions of this method to multiple-criterion autopilot design problems are also discussed. The approach considered provides a constructive algorithm to design a multiple-criterion controller and offers new insights into the relationship between multiple H₂/H^∞ and multiple H ^∞/H^∞ designs
