A Switching Approach to Packet Loss Compensation Strategy [PDF]
IEEE Access, 2019 In networked control systems, a zero or hold compensation strategy is usually used for the missing signal when a packet is lost. In this paper, a switching approach is proposed for the consecutive loss compensation, where the packet loss between sensor and controller is modeled as an i.i.d. Bernoulli process.
