摘要：This paper studies a privacy preservation problem in a cloud-based LQG control system. The system consists of a client and a cloud. The client, the service requester, owns a process in need of LQG control input from the cloud, the service provider, who returns the optimal LQG control inputs based on the shared information. Meanwhile, the client deploys a stochastic event-triggered scheduler (SES) to both conserve its communication resources and preserve its privacy. In this paper, the communication performance and the privacy preservation performance are analyzed and its associated parameters are designed. Finally, an example is given to show the feasibility and the privacy preservation performance of the SES.
