This study proposes a novel hierarchical nonlinear proportional-integral fast terminal sliding mode (HNLPIFTSM) control for permanent magnet synchronous motor (PMSM) speed regulation system. A new type of surface called HNLPIFTSM surface, which combines the benefits (PI) and (FTSM) is proposed to enhance robustness improved dynamic response, whilst preserving great property conventional (HFTSM)...

ATP13A2 is a lysosomal P-type transport ATPase that has been implicated in Kufor-Rakeb syndrome and Parkinson's disease (PD), providing protection against α-synuclein, Mn(2+), and Zn(2+) toxicity in various model systems. So far, the molecular function and regulation of ATP13A2 remains undetermined. Here, we demonstrate that ATP13A2 contains a unique N-terminal hydrophobic extension that lies o...

This paper addresses an integral sliding mode control approach for automatic generation control (AGC) of a single area power system. Genetic algorithm (GA) is employed to search the parameters of the sliding surface. The proposed design is investigated for AGC of a single area power system, made up of reheated thermal and gas power generations. Compared with the GA-based proportion-integral (PI...

This paper proposes a new sliding surface for controlling Semi-Bridgeless Boost Converter (SBBC) which simultaneously performs Power Factor Correction (PFC) and DC bus regulation. The proposed is composed of three terms: First, normalized voltage error term controls the rejects disturbances. In this case, normalization was performed increasing system robustness during start-up large Second, an ...

Sliding pressure control is a well-known method of controlling supercritical power plants that improves energy efficiency and reduces dynamic stresses. This paper presents novel approach for developing cleaner coal plant’s sliding strategy. First, using Whale Optimizer, nonlinear identified transfer matrix model was created (WO). By comparing simulations errors, the WO clearly outperforms GA Gr...

Two problems: Parameter uncertainty and chattering effect present in Control signal are have a great deal in performance of system with the designed controllers. This paper presents Fuzzy Sliding Mode Controller (FSMC) for Multi Area Load Frequency Control problem or Automatic Generation Control (AGC) in a De-regulated environment. The first problem is addressed by designing a sliding mode cont...

This paper investigates the chaos synchronization problem for a class of uncertain master–slave unified chaotic systems. Based on the sliding mode control technique, a robust control scheme is established which guarantees the occurrence of a sliding motion of error states even when the parameter uncertainty and external perturbation are present. Furthermore, a novel proportional–integral (PI) s...

Suffering from consistent external disturbances and unavailable kinetic dynamics, a data-driven backstepping sliding-mode control (DBSMC) scheme by the combination of technique is innovatively proposed for complex quadrotor unmanned aerial vehicles (QUAVs). To maintain salient advantages traditional PID algorithm, PD-type surface first designed attitude subsystem, thereby contributing to an eff...

The dead-zone nonlinearity and uncertain dynamics inevitably weaken the tracking performance of displacement system for a hydraulic roofbolter. To solve above problem, global sliding-mode controller based on reduced-order proportional-derivative-type (PD-type) extended state observer (GSMC-PDESO) is proposed. Firstly, model roofbolter built by using compensation technique to suppress effect con...

Survival implications of nontuberculous mycobacterial pulmonary disease (NTM-PD) and NTM pulmonary isolation without disease (NTM-PI) are unclear. To study deaths associated with NTM-PD and NTM-PI and differences in survival between them, we conducted a population-based cohort study of persons with microbiologically defined NTM-PD or NTM-PI diagnosed during 2001-2013 in Ontario, Canada. We used...
