Abstract : It is show that the state feedback matrix of a linear system optimal with respect to a quadratic performance index can be expanded in a MacLaurin series in parameters which change the order of the system. The first two terms of this series are employed in an 'optimally sensitive design' for a high-order plant. The result of the optimally sensitive design is superior to that achieved by a conventional low-order design, while the amount of computation is considerably lower than it is required for a high-order design. An example of a second order design for a fifth order plant is given. (Author)
