Abstract

This paper investigates quantized feedback control problems for network empowerment ammunition, where the sensors and the controller are connected by a digital communication network with data-rate limitations. Different from the existing ones, a new bit-allocation algorithm on the basis of the singular values of the plant matrix is proposed to encode the plant states. A lower bound on the data rate is presented to ensure stabilization of the unstable plant. It is shown in our results that, the algorithm can be employed for the more general case. An illustrative example is given to demonstrate the effectiveness of the proposed algorithm.

Abstract

This paper investigates networked control problems for linear control systems, where the sensors and the controller are connected by a bandwidth-limited, noisy digital communication channel with time delays. For this case, we examine the role communication has onquantized feedback stabilization problems, present quantization, coding, and control schemes, and derive a sufficient condition on the data rate of stabilization of the unstable plant. It is shown in our results that, communication constraints have important effectson stabilization of networked control systems. An illustrative example is given to demonstrate the effectiveness of the proposed method. DOI : http://dx.doi.org/10.11591/telkomnika.v12i2.3816
