✦ Synopsis
A noniterative me~:hod for the computation of infimum for a class of continuous-time Ho~ optimal control problem is considered in this paper. The problem formulation is fairly general and does not place any restrictions on any direct feedthrough terms of' the given systems. The method is applicable to systems where (i) the transfer function from the disturbance input to the measurement output is free of imaginary axis invariant zeros and left invertible, and (ii) the transfer function frora the control input to the controlled output of the given system is free of imaginary axis invariant zeros and right invei~ible. The result presented in this paper is a continuation of the previous work of the author and his co-workers (Chert et al., 1992), in which the direct feedthrough term from the disturbance input to the measurement output of the given system are required to be zero.
