一種改進型串級調速系統的研究與設計

摘要：通過對傳統串級調速系統的分析研究，針對其不能實現電氣制動的不足，提出一種改進型串級調速系統的設計方案。利用MATLAB軟件，分別對兩種調速系統的啟動、制動進行仿真驗證。結果表明，改進型串級調速系統不僅能夠實現電氣制動，而且調速性能優于傳統串級調速系統。 敘詞：串級調速 電氣制動 繞線電機 Abstract：By researching on traditional cascade control system, we designed an improved cascade control system because of the fault that the traditional couldnt achieve electric braking. Simulation experiments were conducted in the two speed regulation systems of start and braking. The simulation results indicated that the improved system couldnt only realize electric braking, but also its performance of speed regulation was superior to the traditional system.
