Summary This paper is concerned with event‐triggered control for the switched system with time‐varying delay and dynamic input quantization. The work is aimed at solving the quantizer saturation in the finite‐level quantized control design and the mismatch caused by event‐triggered sampling and the switching. First of all, the quantization parameter updating laws are designed respectively in the case of match and mismatch between the system and the controller under the event‐triggered mechanism without Zeno behavior. Then, the total variation of Lyapunov functional is transformed into discrete time updating of the dynamic quantization parameter. A switching law and a quantized control strategy are developed to ensure the exponential stability of switched systems with delay and input quantization. At last, two examples are given to illustrate the validity of the results.
