Embodiment Construction
[0058] In order to make the objectives, technical solutions and advantages of the present invention clearer, the technical solutions of the present invention are further described below with reference to the accompanying drawings and simulation data.
[0059] refer to Figure 1 to Figure 3 , a security control method for a networked motion control system in a quantitative environment. The method first models the motion control system, considers that the actuators and sensors are attacked at the same time, constructs an intermediate observer, and directly adjusts the value of specific parameters by The influence of quantization is suppressed, and the actuator attack and sensor attack are estimated at the same time, and the intrusion-tolerant controller is designed according to the estimated value, so that the state of the closed-loop system is consistent and eventually bounded.
[0060] The present invention is a safety control method for a networked motion control system in a ...
