In this paper a novel concept of event triggering control (ETC) for effective resource utilization is proposed for dc microgrid. Matched uncertainty elimination is possible through sliding mode control (SMC) itself as addressed in the literatures. This paper proposes a new approach for suppression of both matched and unmatched uncertainties in grid connected and islanded mode through an integral disturbance observer (IDO) which is designed with super twisting SMC to provide dual filtering phenomena pertaining to system perturbations. The IDO facilitates control algorithm to manage effective event counts during disturbance conditions. The proposed controller is designed in order to regulate DC bus voltage and enhance the microgrid capability to perform stable operation in presence of uncertainties. Chattering free finite time convergent SMC is designed with super twisting reaching law to obtain robust behavior of dc microgrid. Results are compared with power rate reaching SMC, Nonlinear disturbance observer (NDO) based controller and PI controller. In the proposed work event triggering condition is designed first time under super twisting reaching law. Comparative assessment is accomplished in lieu of demonstrating the superior performance of event trigger SMC through MATLAB/Simulink and Typhoon based controller hardware in loop (CHIL) platform.

具有匹配/不匹配干扰观测器的直流微电网事件触发超扭曲滑模控制

本文提出了一种用于直流微电网的有效资源利用的事件触发控制（ETC）的新概念。如文献所述，可以通过滑模控制（SMC）本身来消除匹配的不确定性。本文提出了一种通过积分扰动观测器（IDO）抑制电网连接和孤岛模式下匹配和不匹配不确定性的新方法，该系统与超扭曲SMC设计在一起，可提供与系统扰动有关的双重滤波现象。IDO有助于控制算法在干扰情况下管理有效事件计数。设计提出的控制器是为了调节DC总线电压并增强微电网在存在不确定性的情况下执行稳定运行的能力。设计具有超扭曲到达定律的无抖动有限时间收敛SMC，以获得直流微电网的鲁棒性能。将结果与达到SMC的功率率，基于非线性干扰观测器（NDO）的控制器和PI控制器进行比较。在拟议的工作事件中，触发条件是在超扭曲到达定律下首次设计的。比较评估是通过MATLAB / Simulink和基于台风的基于控制器的硬件在环（CHIL）平台来证明事件触发SMC的卓越性能而完成的。在拟议的工作事件中，触发条件是在超扭曲到达定律下首次设计的。比较评估是通过MATLAB / Simulink和基于台风的基于控制器的硬件在环（CHIL）平台来证明事件触发SMC的卓越性能而完成的。在拟议的工作事件中，触发条件是在超扭曲到达定律下首次设计的。比较评估是通过MATLAB / Simulink和基于台风的基于控制器的硬件在环（CHIL）平台来证明事件触发SMC的卓越性能而完成的。
