摘　　要：在信息受限条件下,研究了一类非线性离散系统的镇定问题.给出了为实现镇定目标而对信号传输过程中编码器和解码–控制器的具体设计以及对信道容量的要求.采用线性矩阵不等式给出了该设计方案的一个充分条件.同时,在不考虑控制输入的情况下,得出系统可检测的结论.数值例子说明所给方法的有效性.The stabilization is studied for a class of nonlinear discrete-time systems with communication constraint. A sufficient condition for the stabilization is presented in terms of linear matrix inequalities. A stabilizing coder-decoder- controller is then developed and the requirement for the channel capacity is also derived. In addition, a corollary of the system observability is deduced for zero input. Finally, an example is given to illustrate the efficiency and feasibility of the proposed approach.
