In this paper, an adaptive nonlinear controller is designed for rotor Surface Permanent Magnet Synchronous Motor (SPMSM) drive on the basis of Input-Output Feedback Control (IOFC), and Recursive Least Square (RLS) method. The RLS estimator detects the motor electromechanical parameters, including the motor iron loss resistance online. Moreover, a Sliding-Mode (SM) observer is developed for onli...

This paper describes the robust optimal incremental motion control of a current  sensorless synchronous reluctance motor (SynRM), which can be specified by any desired speed profile. The control scheme is a combination of conventional linear quadratic (LQ) feedback control method and sliding mode control (SMC). A novel sliding switching surface is employed first, that makes the states of the Sy...

sulfur mustard (sm) is a chemical warfare agent which was widely used in the world war i and more recently during gulf war in the early 1980s'. sm is a strong alkylating agent with known mutagenic and carcinogenic effects but only few studies have been published on its teratogenicity. since sm has been widely used as a chemical weapon by the iraqi regime against the iranian soldiers as well as ...

We study heavy physics effects on the Higgs production in γγ fusion using the effective Lagrangian approach. We find that the effects coming from new physics may enhance the standard model predictions for the number of events expected in the final states b̄b, WW , and ZZ up to one order of magnitude, whereas the corresponding number of events for the final state t̄t may be enhanced up to two orde...

Chemical warfare agents are the most brutal weapons among the weapons of mass destruction. Sulfur mustard (SM) is a potent toxic alkylating agent known as “the King of the Battle Gases”. SM has been the most widely used chemical weapon during the wars. It was widely used in World War I. Thereafter, it was extensively employed by the Iraqi troops against the Iranian military personnel and even c...

We use the discrete phenomenological model to study theoretically the phase diagrams in antiferroelectric liquid crystals (AFLCs) as a function of optical purity and temperature. High sensitivity of the phase sequence in the AFLCs to optical purity is attributed to the piezoelectric coupling which is reduced if optical purity is reduced. We limit our study to three topologically equal smetic (S...

The pharmacokinetics of cefpiramide (SM-1652) were studied after the intravenous administration of single or multiple doses to 21 healthy volunteers. The cefpiramide concentration in plasma at time zero after a bolus intravenous injection of 500 or 1,000 mg was 152 or 303 micrograms/ml, respectively. The maximum cefpiramide level in plasma at the end of a 1-h infusion of 1,000 or 2,000 mg was 1...
