摘要:
针对传统直接转矩控制所固有的稳态运行时转矩、磁链、电流脉动大的问题,提出了一种利用转矩误差与磁链误差、通过滑模变结构控制方法实现对转矩与磁链进行控制的直接转矩控制方案。分别以转矩误差与磁链误差作为状态变量设计了时变积分型滑模平面,保证了趋近过程的系统状态保持在滑模面附近,减小了趋近距离。而对于滑模变结构控制本身的抖振问题,采用了一种通过滞环比较器自适应地实现了滑模变结构控制与传统PI控制的平滑过渡的混合滑模变结构控制方法。实验结果验证了该控制方法的有效性和可行性。
Abstract:
For its inherent drawbacks of classic Direct Torque Control(DTC),such as torque,flux,and current ripple,a novel DTC scheme is presented,in which a sliding mode variable structure control(SMVSC) method is applied to control electromagnetic torque and stator flux by using torque and flux errors,in order to preserve the system states near the sliding-mode surface and reduce the reaching distance.For its intrinsic chattering of SMVSC,it suggested a hybrid sliding-mode variable structure control(HSMVSC) method,in which variable structure control(VSC) could smoothly transit to classic PI control by hysteresis comparator adapted.The experiment results verify its validity and effectiveness.
