In this paper, we propose a robust hybrid control for a boost inverter. This control presents the particularity of considering the real nature of the dynamics , which means, the continuous-time dynamics, voltages and currents, and the discrete-time dynamics, the switching of the transistors. Likewise, due to implementation issues a minimum dwell time is introduced in the control loop scheme. Uniform global asymptotic stability is guaranteed, ensuring that the tracking error of the system output enters into a small neighbourhood of zero. Moreover, robustness guarantee with respect to parameter variations, in terms of an error tracking output regulation, are also provided here. The effectiveness of the proposed hybrid control scheme is illustrated in simulation.

升压逆变器的鲁棒混合控制律

在本文中,我们为升压逆变器提出了一种鲁棒的混合控制。这种控制呈现出考虑动态特性的特殊性,即连续时间动态特性、电压和电流,以及离散时间动态特性、晶体管的开关。同样,由于实施问题,在控制回路方案中引入了最小停留时间。保证全局渐近稳定,保证系统输出的跟踪误差进入一个很小的零邻域。此外,这里还提供了在误差跟踪输出调节方面关于参数变化的鲁棒性保证。仿真说明了所提出的混合控制方案的有效性。
