摘 要：In this paper, we study the optimal tracking performance problem of continuous-time linear multi-input multi-output（MIMO） networked control systems. The unstable and non-minimum phase systems is considered. The output feedback path is subject to quantization noise, additive white Gaussian noise and bandwidth constraints, and encoding and decoding are considered. The reference input is a random signal. The performance is measured through the tracking error energy, and two-parameter controller is considered. The explicit expression of the tracking performance has been obtained. The results show that the unstable poles and non-minimum phase zeros of the plant, the channel noise,bandwidth, quantization noise and coder will aggravate the optimal tracking performance.
