Stabilization of Multi-rate Sampled-data Nonlinear Systems with Quantization
具有量化误差的多步长非线性采样系统的镇定

This paper investigates multi-rate sampled-data stabilization of nonlinear control systems while the sampler produces quantization during sampling. The approximate DTD method is employed to design a (globally) stabilized controller based on the approximate discrete-time models of the nonlinear plant. It is shown that the multi-rate sampled-data nonlinearcontrolsystemswith quantizationareguaranteedtobe semi-globallypracticalasymp-totically stable while the approximate error and quantization level are restricted by a certain error condition. A simulation example illustrates the validity of obtained results.
