一種改進(jìn)型串級調(diào)速系統(tǒng)的研究與設(shè)計

摘要：通過對傳統(tǒng)串級調(diào)速系統(tǒng)的分析研究，針對其不能實現(xiàn)電氣制動的不足，提出一種改進(jìn)型串級調(diào)速系統(tǒng)的設(shè)計方案。利用MATLAB軟件，分別對兩種調(diào)速系統(tǒng)的啟動、制動進(jìn)行仿真驗證。結(jié)果表明，改進(jìn)型串級調(diào)速系統(tǒng)不僅能夠?qū)崿F(xiàn)電氣制動，而且調(diào)速性能優(yōu)于傳統(tǒng)串級調(diào)速系統(tǒng)。 敘詞：串級調(diào)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.
