“…absence of disturbances; performance in [7], [8] is measured by an average quadratic cost just as in traditional Linear Quadratic Gaussian control. Other works have proposed ETC strategies, relying on different ideas, that can achieve a better performance than that of periodic control for the same average transmission rate (first consistency property) [5]- [7], [9], [11], [12]. However, all these works consider that full state-feedback is available, and, to the best of our knowledge, only [11] has been extended to output-feedback, see [13], [14] and also [15].…”
