In response to the challenges posed by the large scale, high integration, and high potential safety risks of existing chemical equipment, a distributed fault-tolerant control method for array-integrated distillation systems is proposed. This method leverages the network topology among cluster units to enable collaboration and information sharing among the units. Moreover, a dynamic event-triggered mechanism is applied to avoid the waste of system communication resources. Additionally, the virtual actuator fault compensation mechanism is proposed to mitigate the impact of actuator faults, and sufficient conditions under actuator faults for the consistency and stability of system are demonstrated. The fault-tolerant controller gain of the array-integrated distillation system is solved using a simulation toolbox. Finally, by integrating traditional distributed control and decentralized control theories, simulations and comparative analyses of the system control method are conducted. The results prove that the proposed distributed fault-tolerant control algorithm is effective, and can significantly enhance the saving rate of system communication resources.
