The bank angle is regarded as the control variable. A novel nonlinear compound controller is designed to make the system with the trajectory-tracking error and its rate as states be input-to-state stable (ISS) with respect to uncertainties. The terminal sliding mode controller is designed to ...
HIV-1 Vpu targets the host cell proteins CD4 and BST-2/Tetherin for degradation, ultimately resulting in enhanced virus spread and host immune evasion. The discovery and characterization of small molecules that antagonize Vpu would further elucidate the
We organize the reminder of the paper as follows: In Section 2, we give the formula of the considered detection problem. We design three new subspace signal detectors in Section 3. In Section 4, we carry out experiments based on real data and simulated data to test the detection performance...
