Abstract: In order to solve the problem of mismatch exist between angular motions by Sustained-G Flight Simulator pilot through his proprioceptive receptors and visual receptors, the control algorithm of Sustained-G Flight Simulator is designed. The formulas relative to control input is derived; the mathematical model of human proprioceptive system is researched, the relationship between pilot's perceptual angular and rotating linear acceleration vectors and angular accelerations is given, based on that, the control algorithm of Sustained-G Flight Simulator is proposed, which can make a match existence between the angular motion perceived by Sustained-G Flight Simulator pilot and aircraft pilot. The simulation …

Abstract: To make the trolley of bridge crane move stably with smooth acceleration, a polynomial acceleration trajectory is proposed based on the constraint conditions of the crane and the friction between the trolley and the rail. An anti-swing plan is designed employing the dynamic coupling relationship between the motion of the trolley and the load swing. Results indicate that when the length of the rope is changed, the swing angle of the trolley is still within the limits. The stability of the system is proved by constructing Lyapunov energy equations, and the Barbalat lemma confirms that the planned reference trajectory …

Signal Processing In Recursive Rejection Filters In The Transient Mode, Dmitrii Popov, Sergey Smolskiy
Turkish Journal of Electrical Engineering and Computer Sciences
A recursive rejection filter (REF) oriented to the radar signal extraction from the moving targets on a background of passive interference in the form of undesired re ections from fixed or slowly moving objects (so-called clutter) is the object under investigation. By means of the state variable method, which gives the adequate filter description in the time domain, the REF structure in the transient mode is synthesized, which is improved with the aim of transient acceleration with the clutter edge arriving. The REF structure's improvement in the transient mode is achieved by its reconfiguration, which is made by REF output …
