Quantized Feedback Control for Nonlinear Feedforward Systems
This paper investigates the quantized feedback control for nonlinear feedforward systems with unknown control coefficients and unknown growth rates. The unknown control coefficients are assumed to be bounded, and the unknown growth rate is time-varying. Based on the wellknown backstepping method and the sector bound approach, a time-varying quantized feedback controller calculated from the quantized output is designed, which can achieve the boundedness and convergence of the closed-loop system states. Moreover, a guideline is provided for choosing the parameters of the quantizers. Finally, a simulation example is given to show the effectiveness of the control scheme.
