A novel reinforcement deep learning deterministic policy gradient agent-based sliding mode control (DDPG-SMC) approach is proposed to suppress the chattering phenomenon in attitude for quadrotors, presence of external disturbances. First, dynamics model quadrotor under study derived, and problem described using formulas. Second, a controller, including its surface reaching law, chosen nonlinear dynamic system. The stability designed SMC system validated through Lyapunov theorem. Third, (RL)...

The pool-type demonstrative China Fast Reactor 600 (CFR-600) adopted a series of improved safety designs, among which the hydraulic suspended passive shutdown subassembly (HS-PSS) is employed for inherent enhancement, especially suitable against unprotected loss flow accident (ULOF). In this article, functional requirements HS-PSS design in hydro-dynamic aspects are proposed, with corresponding performance indicators discussed. To address these requirements, qualitative analysis on...
