摘要
以一种可扩展单元的高增益升压Cuk变换器为研究对象,提出一种基于线性自抗扰改进单周期控制策略。采用线性自抗扰控制策略与单周期控制技术相结合的一种控制方式,以解决Cuk变换器在受到系统干扰时,单周期控制技术对于系统非线性特性以及时变扰动的作用有限的问题。与其他控制方法相比,保证了系统大信号稳定以及在受扰动时的快速恢复性能。对所提出控制策略进行仿真和实验研究表明,与传统的单周期控制相比,所提策略能更有效的抑制系统扰动,使系统具有更良好的鲁棒性。
Taking a high gain boost Cuk converter with scalable unit as the research object,an improved single-cycle control strategy based on linear active disturbance rejection is proposed.A control method combining linear active disturbance rejection control strategy and single-cycle control technology is adopted to solve the problem that the single-cycle control technology has limited effect on the nonlinear characteristics and time-varying disturbance of Cuk converter when it is disturbed by the system.Compared with other control methods,the stability of large signal and the rapid recovery performance in case of disturbance is ensured.The simulation and experimental results show that the proposed control strategy can suppress the system disturbance more effectively and make the system more robust than the traditional single-cycle control.
