摘 要: | 针对我国部分矿井提升机调速系统效率低、成本高、能源浪费、谐波污染大的现状,提出了一种新型的双PWM变频调速系统的设计方案。设计了一种基于滑模控制的PWM整流器,其电压外环采用滑模变结构控制,电流内环采用前馈解耦控制,并利用空间脉宽矢量调制(SVPWM)算法提高直流电压利用率。仿真结果证明了该方案的有效性。

Abstract: | Most of our country coal mine hoist control system is noted by high cost,low efficiency,energy wasted and harmonic pollution.In order to change the situation,proposes a design scheme of new type of dual-PWM frequency-conversion speed-regulation system with the space vector pulse modulation,it uses the sliding mode control as the voltage loop and current feed-forward decoupled control algorithm as the current-loop.The simulation result verifies the validity of the scheme. |
