摘要：

The present article deals with the problem of evaluating the effects of quantization on a nonlinear sampled-data control system. The control strategy is based on a suitable digital design of "backstepping" type controllers and it was proposed in a previous article. The advantage of this design is that it preserves, under sampling, the stabilizing performances imposed in the continuous-time design. The control solution comprises heavily nonlinear expressions and to study the effects of quantization is strongly requested This work captures the contributions of the sampling period, of the degree of controllers' approximations and of the numerical precision in the performance of a sampled-data controller.
