The experiment result shows that the digital control system based on TMS320LF240 7A is reliable and free from load disturbance,not only can meet the requirement of real time control,be convenient to realize any advanced control strategy,but also is simple,high reliable and has high application worth.
This implies that a system is algebraically integrable (i.e., its eigenvalue problem is explicitly solvable in quadratures) if and only if the differential Galois group is commutative for generic eigenvalues.
In the second example, we obtain a proof of the Chalyh-Veselov conjecture that the Calogero-Moser system with integer parameter is algebraically integrable, using the results of Felder and Varchenko.
We consider 3-parametric polynomialsPμ*(x; q, t, s) which replace theAn-series interpolation Macdonald polynomialsPμ*(x; q, t) for theBCn-type root system.
An electronic circuit which may be applied to the control of firing angle of high voltage mercury arc current converter is suggested in this paper.The circuit mainly consits of two parts:the primary pulse generator and the secon- dary pulse former.Between these two parts is inserted an insulating transfo- rmer which transmits the control paise and isolates the high potential difference between them.The primary generator generates the control pulses and determinates their phase.The secondary pulse former sup...
In this paper, the method of excitation regulation according to voltage deviation with a high coefficient of amplification is investigated, with an analysis of stability and instability regions, a study of the excellent effect of such regulation in improving the stability of electric power systems, and a discussion of the restrictions on its application imposed by the time constants of the exciter and the regulator.The effects of introducing into the regulating system the first and the second de...
The author attempts to derive the transmission loss formula for a rather complicated power system having multiple load points. He has analyzed thoroughly systems of various patterns possibly obtained from network reduction, and has succeeded in expressing the total transmission loss as a sum o?those resulting from the transfer of incremental power from each source to the various load points. As a result of this, it will be possible to coordinate the incremental transmission loss with the increme...
