摘　　要：分析采用准滑模控制方案的感应加热串联谐振逆变器,建立逆变器的负载回路离散数学模型,其中包括切换面参数的选取、到达条件的证明和稳定性分析。仿真结果表明,滑模控制方法可有效改善系统动态特性和增强其对外部干扰的鲁棒性,证明其控制方案的可行性和正确性。The analysis literature about the establishment of mathematic model of series resonant converter for induction heating based on quasi- sliding mode variable structure control, including the selection of the switch surface parameters, certification of the reachable condition and analysis of stability. Simulation results show the sliding mode control possessed of a better dynamic performance and improved robustness to the external perturbations. Results validate the effectiveness of pro- posed control method.
