Maximum achievable precision of linear systems with discrete controllers

摘要: Consideration was given to the problem of maximum achievable precision linear systems with discrete state and output controllers. The external perturbations affecting system are bounded step-type harmonic (of unknown frequency) vector functions time which control theory regards as standard. condition for asymptotic stability closed-loop is only requirement on controllers aside from their physical realizability. Therefore, conclusions present paper apply entire set stabilizing controllers, no matter what method used design them.
