In this paper, we propose a new approach to the attitude control of quadrotors, by which angular velocity measurements or model-based observer reconstructing are not needed. The proposed is based on recent stability results obtained for nonlinear negative imaginary systems. specific, through an inner-outer loop method, establish property quadrotor rotational subsystem. Then, strictly controller...

In this study, we discuss the negative decision concept as legal characterization approved by Law for Administration's abstention or refusal to issue a decision, which is obligated give in accordance with laws and regulations. The study aims determine possibility of challenging its position re-coursing if Administrative Authority fails perform duty Circumvent manner that prejudices individuals’...

This paper proposes a consensus-based formation tracking scheme for multi-robot systems utilizing the Negative Imaginary (NI) theory. The proposed applies to class of networked robotic that can be modelled as group single integrator agents with stable uncertainties connected via an undirected graph. NI/SNI property facilitates design distributed Strictly (SNI) controller achieve desired trackin...

Self-control often fails when people experience negative emotions. Negative urgency represents the dispositional tendency to experience such self-control failure in response to negative affect. Neither the neural underpinnings of negative urgency nor the more general phenomenon of self-control failure in response to negative emotions are fully understood. Previous theorizing suggests that an in...
