Method for designing event-driven SDOFQ controller under periodic DoS attack

The invention discloses a method for designing an event-driven SDOFQ controller under periodic DoS attack. The method comprises the following steps of: A, establishing an object model, a periodic DoSattack model, a security event driver model and a symmetric logarithm quantizer model; B, establishing a switched dynamic output feedback quantization controller model, and establishing a closed-loopswitching system model under multiple constraints; and C, designing switched dynamic output feedback quantization controller design conditions under multiple constraints, solving a switched dynamic output feedback quantization controller gain matrix, and finally obtaining a switched dynamic output feedback quantization controller meeting system requirements under multiple constraints. According tothe method, the problem that a previous system cannot be stabilized under periodic DoS attack and multiple quantitative constraints is solved; and the periodic DoS attack induced packet loss phenomenon and the sesame phenomeno
