摘要
给出了一种用于X射线管的负高压直流电源原理结构,针对其中的稳压控制回路进行了分析,建立了电压控制回路的数学模型,基于滑模变结构控制理论设计了稳压控制算法。仿真实验表明,所设计的稳压控制系统在稳态性能、动态性能和鲁棒性等方面满足实际要求。
A principle structure for negative high-voltage DC power supply was presented, and the voltage control loop was analyzed. The transfer function model of the voltage control open loop was set up, and the controller was built based on the sliding mode control theory. The simulation experiments show that the voltage control loop meets the design requirements in the performance of steady-state, dynamic and robustness.
