概要: In this paper, we consider the problem of stabilizing the state feedback control systems that have quantizers in feedbac … k loop. We study “the binary expansion quantization” where by using the finite bits measurement signals are endorded. Since there is no assumption on the infinite fineness of the quantizer, asymptotic stability cannot be ensured. However we derive a sufficient condition, in terms of the matrix norm and the matrix inequality form, on a quantization bit rate and gains for the ultimate boundedness of the state of the closed loop.<br />出版者照会後に全文公開続きを見る

概要: In this paper, we consider a blocking zero placement problem for closed-loop systems by state feedback. As a solution to … the problem, we derive a dynamic state feedback controller which can be designed by solving a stabilization problem by constant state feedback. Moreover, we apply the proposed blocking zero placement method to a periodic disturbance rejection problem. Since a transfer function with blocking zeros can eliminate input signals corresponding to these blocking zeros, the periodic disturbance can be rejected if closed-loop systems have corresponding blocking zeros with the period on the imaginary axis.<br />出版者照会後に全文公開続きを見る
