Abstract:

A method for determining the optimum linear digital control system with respect to a quadratic performance criterion, when additive disturbances are present, is described. A method of designing multivariable, time varying andor final value contrrol ystems is presented. This method of design is also advantageous when optimum control must be maintained during the initial start up transient as no assumption concerning steady state was made. The method of estimating the state variables is extended to the case of independent random sampling but the portion concerned with optimum control of a system constrained at the output is only extended to certain special cases. The design method is also extended to adaptive control systems for the case where perfect identification is possible. Author
