This invention discloses a semi-Markov power system security control method under random DoS attacks, belonging to the field of power system control technology. This invention introduces a logic processor to capture the maximum duration of a DoS attack and calculates the probability of the attack and the resulting maximum allowable number of consecutive packet losses by employing periodic sampling technology. Furthermore, considering the asynchronous behavior between the power system and the controller, a non-homogeneous Hidden Markov Model is used to describe the asynchronous phenomenon, and the uncertain transfer rate matrix is ​​further discussed in two types, which helps to provide a clearer framework. By combining controller control with performance index control, security control of the system can be achieved through static output feedback under random DoS attacks.
