The synthesis of controller algorithm for reversible electromechanical scanner of the telescope scanning axis is discussed. Digital control system is built without intermediate stage of synthesis of analog control law. The modified procedure for the synthesis of discrete optimal control law is introduced. Elasticity influence on static and dynamic characteristics of electromechanical scanner of...

High-spin paramagnetic manganese defects in polar piezoelectric zinc oxide exhibit a simple, almost axial anisotropy and phase coherence times of the order of a millisecond at low temperatures. The anisotropy energy is tunable using an externally applied electric field. This can be used to control electrically the phase of spin superpositions and to drive spin transitions with resonant microwav...

We analyze effects of the hyperfine interaction on electric dipole spin resonance when the amplitude of the quantum-dot motion becomes comparable or larger than the quantum dot's size. Away from the well-known small-drive regime, the important role played by transverse nuclear fluctuations leads to a Gaussian decay with characteristic dependence on drive strength and detuning. A characterizatio...

Nonlinear simulation with a simple resistive magnetohydrodynamics model is used to investigate the stabilization of magnetic fluctuations in reversed-field pinch plasmas subject to pulsedparallel current drive (PPCD). Numerical results are diagnosed with computations of nonlinear power transfer and by evaluating sequences of profiles for linear stability. Results show that poloidal electric fie...

In this paper, an electric vehicle drive with a robust and low cost alternating current (AC) induction motor is presented. This approach is applied to an existing commercial utility electric vehicle where previously used direct current (DC) series motor was replaced by the new AC induction motor. The use of three-phase squirrel cage induction motor requires implementing of voltage source invert...

This paper introduces a new software environment, the Virtual Test Bed (VTB), which has been particularly developed for graphical and visual simulation of large-scale electric power systems. A possible application of the VTB to analysis of an electric drive system is also described.
