Quadratic performance criteria for discrete control systems can be determined either from the time response or by the complex-convolution theorem; both methods being lengthy or limited in their use. By means of Lyapunov's well known matrix equation, a new general method is introduced for the direct definition and evaluation of performance criteria from the system parameters. This method lends itself to a simple digital-computer program.
