The finite-time dissipative control for a class of nonlinear distributed parameter Cyber-Physical Systems (CPSs) is studied in this article. By replacing the nonlinear term with the Takagi-Sugeno (T-S) fuzzy model, the nonlinear distributed parameter CPSs are represented by a fuzzy parabolic partial differential equation (PDE). To reduce the transmission burden of communication channels, the state information is considered to be dynamically quantized before transmission. Then, a fuzzy state feedback controller under cyber attacks is designed. Sufficient design criteria for the fuzzy controller and the adjusting parameters of dynamic quantizer are developed to obtain the finite-time dissipative performance of the fuzzy closed-loop system by the free-matrix inequality approach. Finally, a simulation study in a cascaded of two cylindrical lithium batteries is explored to validate the efficiency of the control strategy.
