In this paper we propose a Fractional Order Controller for an under-actuated system (POAC). This system has two degrees-of-freedom and one control input. The model of the system is derived using Euler Lagrange method and the stabilization is achieved with constraints using Fractional Order Controller. To validate the control law, simulation are performed and compared with Integer Order Controll...

Phase retrieval on well-exposed PC images shows that shrinkage of the OTA continues at a rate of about 0:90 0:15 m=month, close to that determined by FOC measurements. A movement of 5:0 m of the secondary mirror away from the primary is recommended for mid-January, to compensate for the shrinkage occurred since the last mirror movement on June 29, 1994. A program of focus monitoring based on ph...

This work represents a new nonlinear control for the asynchronous motor (AM) drive. The designed is based on combination between backstepping (BC) scheme and third-order sliding mod (TOSMC). In this proposed control, torque flux are controlled. Also, torque, current, ripples minimized by BC-TOSMC strategy. strategy more robust compared to field-oriented (FOC). of AM drive has been simulated in ...

where our definition of Rt+1 helps clarify the relationship of this equation to the usual consumption Euler equation (and you should think about why this is the right definition of the interest factor in this model). Now we show that this FOC is satisfied by a rule that says Ct = γYt, where γ = 1 − αβ. To see this, note first that the proposed consumption rule implies that Kt+1 = (1− γ)Yt. The ...

Two new fluorous photolabile-protecting groups (FNBC and FNB) and a new base-labile protecting group (FOC) for the masking of amines are reported. The protecting groups survive a wide range of common reaction conditions used in oligosaccharide synthesis and render the attached molecules amenable to fluorous solid-phase extraction (FSPE). A glycosyl acceptor containing the FNB group is shown to ...

In this paper, the concept and implementation of field-orientation control (FOC) of a doubly excited brushless reluctance machine (DEBRM) for variable-speed drives and generating systems are presented. A stator-flux-orientation scheme is employed to achieve decoupled control of torque and reactive power. A 2-hp DEBRM prototype system with a digital signal processor (DSP)-based controller and a ...

This study investigates the simple vector control of a 3-phase squirrel cage Induction Motor (IM) under open-circuit fault (faulty 3-phase IM). It was shown that it is needed to supply the stator windings with unbalanced currents to remove the oscillating term of the machine electromagnetic torque. The vector control system is based upon Field-Oriented Control (FOC) that has been adapted for th...

Assume that i q; m; p depends only on pair-wise price di¤erences; this property can be derived from a consumer choice model with quasi-linear preferences in money. where 1 n is a vector of ones of length n: Also, assume that the FOC is su¢ cient to characterize a unique equilibrium for any symmetric cost structure. Let i m; p denote the corresponding vector specifying the probabilities over di¤...
