Discussion on the qd/qd model of slip energy recovery drive

Hildebrandt, Reference frame analysis of a slip energy recovery system, IEEE Trans. Energy Convers. 3 (2) (1988) 404–408; E. Akpinar, R.E. Trahan, A.D.

Eskadarzadeh, H. ?nce, Modelling and output power optimization of a wind turbine driven double output induction generator, IEE Proc. Electr. Power Appl. 141 (2) (1994) 33–38]. The steady-state solution is provided in [P.C. Krause, O.Wasynczuk, M.S. Hildebrandt, Reference frame analysis of a slip energy recovery system, IEEE Trans. Energy Convers. 3 (2) (1988) 404–408; M.Y. Üçtu?, ?. Eskadarzadeh, H. ?nce, Modelling and output power optimization of a wind turbine driven double output induction generator, IEE Proc. Electr. Power Appl. 141 (2) (1994) 33–38]. A fourth and fifth order transient models are obtained in [E. Akpinar, R.E. Trahan, A.D. Nguyen, Modeling and analysis of closed-loop slip energy recovery induction motor drive using a Linerizatio technique, IEEE Trans. Energy Convers. 8 (4) (1993) 688–697; S.A. Papathanassiou, M.P. Papadopoulos, State-space modeling and eigenvalue analysis of slip energy recovery drive, IEE Proc. Electr. Power Appl. 144 (1) (1997) 27–36], respectively. These models can be used to predict the performance, when the effect of overlap angle and rectifier input current harmonics are ignored, and the rectifier input power factor is also assumed to be unity. In this paper, both models are solved in Matlab and results are compared to the results of Simulink model of the SERD.     

Memristor‐based voltage‐controlled relaxation oscillators

This paper introduces two voltage‐controlled memristor‐based reactance‐less oscillators with analytical and circuit simulations. Two different topologies which are R‐M and M‐R are discussed as a function of the reference voltage where the generalized formulas of the oscillation frequency and conditions for oscillation for each topology are derived. The effect of the reference voltage on the circuit performance is studied and validated through different examples using PSpice simulations. A memristor‐based voltage‐controlled oscillator (VCO) is introduced as an application for the proposed circuits which is nano‐size and more efficient compared to the conventional VCOs.

Impact of TMS on the primary motor cortex and associated spinal systems.

Repetitive transcranial magnetic stimulation (rTMS) is able to modulate corticospinal and intracortical motor cortex excitability, depending on the stimulation parameters. In the present study, we explored the effects of highand low-frequency rTMS on spinal reflex monosynaptic responses (H waves or H reflexes) in humans recorded from the flexor carpi radialis (FCR) muscle. After 1-Hz rTMS, H-wave minimal and optimal thresholds were decreased by 14-22% of their pre-rTMS values. The maximal H-wave and H/M amplitude ratio were both significantly increased by 52-54%, whereas direct muscle responses (M waves) remained unchanged. The area under the H-wave recruitment curve was also significantly increased by 86 /spl plusmn/ 21% of its pre-rTMS baseline values. Conversely, after 20-Hz rTMS, H-wave minimal and optimal thresholds were both increased by 15-26%. The maximal H wave and H/M amplitude ratio were significantly decreased by -37 /spl plusmn/ 11%, whereas M responses remained unchanged. The area under the H-response recruitment curve was also significantly decreased by -45/spl plusmn/5%. Neither 20-Hz nor 1-Hz sham rTMS induced noticeable changes in M or H responses. We conclude that 1-Hz rTMS applied to primary motor areas increases the monosynaptic spinal cord H reflex, whereas 20-Hz rTMS induces the opposite effect, presumably by modulating inhibitory descending conicospinal projections onto spinal motoneurons. These results offer an opportunity to influence the level of spinal excitability and modify descending corticospinal influences in a controlled manner using noninvasive approaches that could prove useful in the study of the pathophysiology and eventual treatment of spasticity.
