The invention discloses a security immunity control method for a heterogeneous unmanned cluster system under distributed denial of attack. According to the method, an event triggering mechanism is adopted, so that continuous information interaction between followers is avoided, discrete communication is realized, a sesame phenomenon is effectively eliminated, and the limitation of limited communication bandwidth under an actual condition is eliminated; in addition, the design requirement for a distributed observer in a traditional method is eliminated, and extra information transmission caused by state variables of the observer is avoided. A controller is designed based on a matching thought to get rid of a system model prior information constraint, and state tracking can be realized under the conditions that the system model is uncertain and different communication links suffer from independent attacks; meanwhile, the equivalent attenuation rate of the communication channel is introduced, the attenuation condition is analyzed under the condition that each communication link is subjected to independent attacks, and the uncertainty of a system model and the diversity of network attacks in the actual situation are effectively dealt with.

This application provides a display panel and display device, including: a display area, a first non-display area, and a second non-display area. The display area surrounds the first non-display area, and the second non-display area surrounds the display area. The display panel includes multiple touch electrodes, and the first non-display area is provided with multiple first touch terminals. Touch signal lines are electrically connected to the first touch terminals and the touch electrodes. Touch signals can be transmitted using the touch electrodes in the touch layer, and then transmitted to the first touch terminals disposed in the first non-display area via the touch signal lines. The first non-display area has sufficient design space to accommodate multiple first touch terminals, enabling various design requirements for the touch terminals. Furthermore, placing the touch terminals in the first non-display area can additionally increase the number of touch terminals, and the size of the touch terminals is not limited by narrow steps. This satisfies the display panel's design requirements for narrow steps in multiple directions without affecting the display effect of the display panel.
