In this article, the design problem of an event‐triggered composite anti‐disturbance dissipative control (ECADC) based on nonlinear disturbance observer (NLDO) is considered for a class of nonlinear stochastic systems. These systems comprise quantized inputs and multiple noises including nonlinear disturbances and multiplicative noises. First, a NLDO‐based control scheme is constructed to estimate and then compensate the noise modeled by the nonlinear exosystem. Then, an event‐triggered scheme and a quantized input technique are adopted to alleviate the channel transmission pressure. Subsequently, by combining dissipative control theory, an ECADC design method is developed such that the closed‐loop system is dissipative in the presence of multiple noises. Finally, the effectiveness of the proposed control scheme is validated through numerical simulations.
