Based on the investigation with several voltage control methods, such as venturini method, instantaneous double - voltage synthesis method and space vector modulation method ( svm ), three new control strategies are put forward. firstly, a time - varying modulation coefficient svm method is proposed to improve mc ' s anti - disturbance performance under the asymmetry input voltage. secondly, a 5 - state switching strategy is presented for mc controlled by the svm method, which reduces the commutation number and switching losses remarkably
在分析了venturini控製法、瞬時雙電壓法、空間矢量法等電壓控制方法的基礎上，提出了在非對稱輸入條件下矩陣變換器空間矢量法的時變調制比改進控制策略，提高了變換器的抗干擾性能；對空間矢量法的開關策略進行了研究，提出了新型5狀態開關策略，在保證其他性能不受影響的條件下，減少了變換器的換流次數和開關損耗；提出了一種矩陣變換器單電壓合成的新方法，它不僅使得變換器的控制簡單，計算量減少，而且使得開關損耗達到最少。 -
The deh system can easily changes the static curve, and makes the transfer from difference to non - difference control. that the pid controller coefficient of deh system can easily adjust according to the experiment make dynamic characteristic better, and can make a brief overopen for good first frequency modulation ability

( 3 ) total coefficient of modulation of moment for the frame applied horizontal load and vertical load is bigger than that of the same frame applied vertical load
（ 3 ）框架既承受水平荷載又承受豎向荷載時的總彎矩調幅系數比相同結構只承受豎向荷載的總彎矩調幅系數大。 -
So, for the design of prestressed frame, the later coefficient may be considered as the parameter of modulation of moment and the moment modulated is the moment caused by the vertical load plus the one by the horizontal load
因此，在預應力框架設計中，可以取只承受豎向荷載的彎矩調幅作為其調幅標準，調幅彎矩為豎向荷載產生的彎矩與水平荷載產生的彎矩之和，即用最小的彎矩調幅系數來調整截面的彎矩。 -
At last, with the program, 18 one - storey and one - span prestressed frames are simulated. some conclusions are reached with the taking into account the, secondary moment and types of load applying : ( 1 ) the in the beam affects the ductility of the section and rotary property of the plastic hinge. so total coefficient of the modulation of moment becomes less with the becoming bigger
最後，本文利用編制的非線性程序，模擬了18榀單層單跨預應力框架，重點研究截面相對受壓區高度、次彎矩、加載方式對塑性內力重分佈和彎矩調幅的影響，從中得出了以下主要的結論和規律： （ 1 ）框架梁相對受壓區高度在很大程度上反映了截面的延性，體現了塑性鉸的轉動能力，框架的總彎矩調幅系數隨著相對受壓區高度的增大而減小。 -
( 2 ) if secondary moment is taken for one kind of modulation of moment and there are the same, the effect of secondary moment on the modulation of moment becomes bigger with secondary moment becoming bigger. if prestressed frame can not complete full redistribution of internal force, ultimate load may put off and put up because of secondary moment. total coefficient of modulation of moment also is bigger
（ 2 ）如果把次彎矩看著是對框架的一種彎矩調幅，在相同的相對受壓區高度下，次彎矩越大，次彎矩調幅作用越強；如果結構不能實現完全的內力重分佈，則次彎矩能夠延緩截面極限承載力的到來，提高結構的極限承載力，結構總的彎矩調幅系數也隨著次彎矩的增大而增大。 -
4 ) as designing, modulation of the secondary moment must be considered. but when the secondary moment is very great, the whole secondary moment as modulation is unfit. there maybe have a fit reducing coefficient
（ 4 ）設計調幅時，需考慮次彎矩調幅，但當次彎矩很大時，把次彎矩完全作為調幅是不適當的，應當有一相應的折減系數。
