This paper investigates the one-bit function perturbation (OBFP) impact on robust set stability of Boolean networks with disturbances (DBNs). Firstly, dynamics these are converted into algebraic forms utilizing semi-tensor product (STP) method. Secondly, OBFP’s DBNs is divided two situations. Then, by constructing a state and defining an index vector, several necessary sufficient conditions to guarantee that DBN under OBFP can stay stable unchanged provided. Finally, biological example proposed demonstrate effectiveness obtained theoretical results.
