Time-domain criteria for theL_{2}-stability of nonstationary feedback systems

M. Sundareshan, M. Thathachar
1973 IEEE Transactions on Automatic Control  
Criteria for the L-stability of linear and nonlinear timevarying feedback systems are given. These are conditions in the time domain involving the solution of certain associated matrix Riccati equations and permitting the use of a very general class of Lroperators as multipliers.
