摘要

针对高升压准z源dc-dc升压变换器(HSQZSC)控制系统由于外界条件的不确定性和干扰导致的动态调节能力差的问题，设计了积分滑模(ISM)控制器，保证了系统的鲁棒性和快速响应。首先，分析了HSQZSC的工作原理，建立了数学模型。其次，以输出电压误差、电感电流误差及其积分为状态变量，设计了滑动曲面;然后，推导了ISM稳定运行的条件，并对其参数设计进行了分析。最后，通过仿真和实验平台与传统控制策略的比较，验证了所设计的ISM控制策略的可行性和有效性。

Research on HSQZSC converter with integral sliding mode control

To address the issue of poor dynamic regulation caused by uncertainties and disturbances in the external conditions of the High step-up quasi-Z-source dc-dc boost converter (HSQZSC) control system, an integral sliding mode (ISM) controller is designed to ensure system robustness and fast response. Firstly, the operating principle of HSQZSC is analyzed to establish a mathematical model. Secondly, a sliding surface is designed using the output voltage error, inductor current error, and their integrals as state variables. Then, the conditions for stable operation of ISM are derived, and the parameter design is analyzed. Finally, by comparing with conventional control strategy using simulation and experimental platform, the results demonstrate the feasibility and effectiveness of the designed ISM control strategy.

期刊介绍： An aim of ELEX is rapid publication of original, peer-reviewed short papers that treat the field of modern electronics and electrical engineering. The boundaries of acceptable fields are not strictly delimited and they are flexibly varied to reflect trends of the fields. The scope of ELEX has mainly been focused on device and circuit technologies. Current appropriate topics include: - Integrated optoelectronics (lasers and optoelectronic devices, silicon photonics, planar lightwave circuits, polymer optical circuits, etc.) - Optical hardware (fiber optics, microwave photonics, optical interconnects, photonic signal processing, photonic integration and modules, optical sensing, etc.) - Electromagnetic theory - Microwave and millimeter-wave devices, circuits, and modules - THz devices, circuits and modules - Electron devices, circuits and modules (silicon, compound semiconductor, organic and novel materials) - Integrated circuits (memory, logic, analog, RF, sensor) - Power devices and circuits - Micro- or nano-electromechanical systems - Circuits and modules for storage - Superconducting electronics - Energy harvesting devices, circuits and modules - Circuits and modules for electronic displays - Circuits and modules for electronic instrumentation - Devices, circuits and modules for IoT and biomedical applications
