Linear Analysis of Zero-Lift Pitching Moment Coefficient and Gravity Effects on Missile Autopilots
Ovec, Naz T.; Erer, Koray S.; Kutay, Ali Türker (2015-03-14)
The most of the studies on disturbance rejection are covered with robust control methods, where this paper suggests a narrowed but a more simplified linear model based technique to assess the robustness of the controllers. In this paper presented, the problems originated from the disturbances are aimed to be obtained as far in advance as possible. The method used in this work reduces the iterative fine tuning time course between the non-linear simulation and the linear model; hence it enhances the authority...
Quantitative measures of observability for stochastic systems
Subaşı, Yüksel; Demirekler, Mübeccel; Department of Electrical and Electronics Engineering (2012)
The observability measure based on the mutual information between the last state and the measurement sequence originally proposed by Mohler and Hwang (1988) is analyzed in detail and improved further for linear time invariant discrete-time Gaussian stochastic systems by extending the definition to the observability measure of a state sequence. By using the new observability measure it is shown that the unobservable states of the deterministic system have no effect on this measure and any observable part wit...

Modelling and control of a wind energy conversion system
Sarıbatır, Behçet M.; Sezer, Mesut E. (Informa UK Limited, 1987-7)
The dynamical model of a novel low power wind energy conversion system consisting of a wind turbine, an induction generator, a PWM a.c. inverter and a d.c. battery group is obtained. A feedback control law is developed to provide optimum power conversion and arbitrarily fast responses at steady-state. The feedback does not require measurement of the wind speed and therefore is suitable for real applications. The stability of the closed-loop system is analysed using a Liapunov-type practical stability criter...
Distributed discrete event simulation architecture with connectors
Çolpankan, İsmet Özgür; Oğuztüzün, Mehmet Halit S.; Kara, Ahmet; Department of Computer Engineering (2014)
In this thesis we propose a distributed approach to Simulation Modeling Architecture (SiMA) with software connectors via Windows Communication Foundation (WCF) as a middleware technology. SiMA is a DEVS-based modeling and simulation framework developed in TUBITAK BILGEM ILTAREN. Discrete Event System Specification (DEVS) is a formalism that arranges complex system models with a well-defined execution protocol. A connector is a first class entity which performs interaction among components and plays an impor...
