Abstract

The invention relates to an unmanned aerial vehicle-trolley formation control method under an all-weather condition. The method comprises the following steps: firstly, constructing a topological structure of an unmanned aerial vehicle-trolley patrol formation, and establishing a state space model of an unmanned aerial vehicle-trolley patrol formation control system on the basis of a Markov model by considering four typical weather conditions and influences of system internal faults and nonlinear interference; by adopting a communication protocol triggered by an adaptive event, communication congestion is relieved, energy consumption is reduced, and a corresponding closed-loop system model is obtained by introducing a control protocol. Then, random stability analysis and consistency analysis are carried out on the closed-loop formation system by utilizing a random analysis method; and finally, solving a feedback gain matrix of the formation control system by using a linear matrix inequality method to obtain a parameter value of the controller. The invention provides an effective control method for all-weather unmanned aerial vehicle-trolley patrol formation.
