Output tracking control of stochastic high-order interconnected nonlinear time-delay systems with input quantization

The tracking control problem of stochastic high-order interconnected nonlinear systems (INSs) is studied with input quantization and time-varying delay. Unlike previous quantized control results, the nonlinearity in this paper satisfies the homogeneous growth condition. In order to mitigate the chattering effect, a hysteretic quantizer is introduced, which is divided into two nonlinear terms. By utilizing adding a power integrator technique, a novel control strategy is presented to ensure all signals in the closed-loop system remain bounded in probability. An example is provided to showcase the efficacy of the developed control strategy.
