“…The problem of gain tuning of PID controller in the turbine governing system is solved by using adaptive grid particle swarm optimization, considering settle time and overshoot level simultaneously (Chen et al, 2015). Additionally, considering the nonlinear characteristics of the HTGS and controller performance improvement, methods such as robust H-infinity control (Qu and Guo, 2021), robust finite-time (Liang et al, 2017), finite-time fuzzy (Huang et al, 2019), fuzzy sliding mode (Wang et al, 2018), fault-tolerant control (Yi and Chen., 2019), and other approaches have been proposed successively (Gil-González et al, 2019; Ma et al, 2018). People are still exploring the high quality control of HTGSs.…”
