Hydraulic support is important equipment in the fully mechanized mining face, and control performance of hydraulic multi-cylinder system directly affects smooth progress coal process, which basis for continuous advancement face. However, friction force process pulling frame complex due to underground environmental load. Moreover, parameters moving cylinder are uncertain, state cannot be measure...

In robotic manipulators, feedback control of nonlinear systems with fast finite-time convergence is desirable. However, because the parametric and model uncertainties, robust tuning manipulators pose many challenges related to trajectory tracking system. This research proposes a state-of-the-art algorithm, which combination integral terminal sliding mode (FIT-SMC), exact differentiator (RED) ob...

A robust control algorithm is always needed to harvest maximum power from a Wind Energy Conversion System (WECS) by operating it consistently at Maximum Power Point (MPP) in the presence of wind speed variations. In this work, Tracking (MPPT) designed via Conventional Sliding Mode Control (CSMC), Super Twisting Algorithm (STA), and Real (RTA) applied Permanent Magnet Synchronous Generator (PMSG...

This paper proposes a Hybrid Backstepping Super Twisting Algorithm for robust speed control of three-phase Induction Motor in the presence load torque uncertainties. First all, squirrel cage is modeled MATLAB/Simulink. then followed by design different non-linear controllers, such as sliding mode (SMC), super twisting SMC, and backstepping control. Furthermore, novel controller designed synergy...

This article aims to realize event-triggered constrained consensus tracking for high-order nonlinear multiagent networks subject full-state constraints. The main challenge of achieving such goals lies in the fact that standard designs [e.g., backstepping, control, and barrier Lyapunov functions (BLFs)] successfully developed low-order dynamics fail work dynamics. To tackle these issues, a novel...

Optical properties of a resonant trilayer metal-dielectric-metal (MDM) structure that consists an upper metal layer, dielectric and substrate are investigated. Using multiple wave interference model, we prove the reflection coefficient MDM may strictly vanish. The existence reflectance zero makes it possible to use as optical differentiator. numerical simulation results presented demonstrate po...
