Abstract Future space programmes pose some interesting research problems in the field of non-Keplerian dynamics, being Moon and cislunar central proposed roadmap for future exploration. In these regards, deployment a station on orbit lunar vicinity is fundamental milestone to be achieved. The paper investigates natural orbit-attitude dynamics attitude stabilisation coupled motions extended bodi...

maintenance is one of the inseparable parts of each industry and relations between this part and others consist of many dynamics and feedbacks. by this regard systems dynamic is a tool that can be used to analyze this part. in this paper for a company that produces wire and cable, cause and effect (feedbacks) between maintenance and others part are modeled. after creating stock-flow diagram, mo...

We present a Concurrent-Learning approach for adaptive control that uses recorded data concurrently with instantaneous data for adaptive flight control. Concurrent learning can guarantee tracking error and weight error convergence to zero subject to a verifiable condition on linear independence of the recorded data; without requiring persistency of excitation in the system states. Simulation st...

Abstract: The paper addresses the design of an autopilot for small scale helicopters to let the vertical, lateral, longitudinal and yaw attitude dynamics to track aggressive references. The paper is mostly focused on robust control aspects of helicopters. In particular the distinguish feature of the control law proposed in the paper is the ability to deal with the presence of possible severe un...

The chattering response at the MRP shadow set switching point for the controlled attitude dynamics of a rigid tumbling spacecraft using delayed state feedback control with MRPs is investigated, where the time delay is assumed to be in the measurement of the state. In addition, a strategy to reduce or completely avoid the chattering phenomena using a hysteretic boundary layer switching rule is e...
