A scheme of quantum feedback control with an optimal cloning machine is proposed.
It is proposed a novel and simple design scheme of output feedback controller for a class of nonlinear systems with delays in the input.
In this paper, we present a device in which the inherent control scheme of force-feedback loops in Σ/Δ-architecture [1] is used for increasing the mechanical sensitivity of differential capacitive inertial transducers in combination with "negative springs".
In the case of the KLT-based CS scheme, the number of feedback bits dramatically increases.
In the proposed scheme, two kinds of feedback information, the quantized low-dimensional CSI index and the compression matrix utilized to perform both compression and recovery, are fed back hierarchically.
Since the number of the feedback times is relevant to the changes of the channel state in the ICASST scheme, the cost of feedback is further evaluated by the feedback frequency, which is defined as the number of the feedback times over the times of the changes of the channel state.
Table 2 Comparison of the transmission schemes in terms of feedback and backhaul loads and computational complexity.
A design scheme of adaptive output feedback based output tracking control system with an adaptively adjusting parallel feedforward compensator is proposed.
The unified control scheme of multi-state feedback control with the zero-placement strategy is shown in Fig. 7, where state x f is a combination of the voltage and current states denoted as x 1, x 2, …, x i with weights f 1 s), f 2 s), …, f i (s), respectively [54].
It can be seen that our proposed scheme (Scheme E with average 12.71 bits of feedback) achieve similar performance as Scheme D that requires 15 bits of feedback.
