This paper presents a method for synchronizing the unified chaotic systems via a sliding mode controller SMC . The unified chaotic system and problem formulation are described. Two identical unified chaotic systems can be synchronized using the SMC technique. The switching surface and its controller design are developed in detail. Simulation results show(More)
Cytosolic phospholipase A2 (cPLA2) plays a pivotal role in mediating agonist-induced arachidonic acid release for prostaglandin (PG) synthesis during stimulation with interleukin-1beta (IL-1beta). However, the mechanisms underlying IL-1beta-induced cPLA2 expression and PGE2 synthesis by canine tracheal smooth muscle cells (CTSMCs) have not been defined.(More)
This paper presents the synchronization between the master and slave Lorenz chaotic systems by slide mode controller (SMC)-based technique. A proportional-integral (PI) switching surface is proposed to simplify the task of assigning the performance of the closed-loop error system in sliding mode. Then, extending the concept of equivalent control and using(More)
This paper considers the problem of the speed control for the Permanent Magnet Synchronous Motor system (PMSMs) based on the quasi-sliding mode control. Based Lyapunov stability theory, the quasi-sliding mode controller and switching function are developed such that the speed of PMSM system can tend to the main desired speed in the quasi-sliding mode. The(More)
BACKGROUND Falling onto the outstretched hand is a major cause of upper extremity injury. The overall objectives of this study were to develop an experimental model for elbow load during a simulated fall onto one-armed arrest using three different forearm axially rotated postures as alternative fall arrest strategies. Additionally, the relationship between(More)
This paper investigates the sliding mode control of chaos problem in permanent magnet synchronous motor (PMSM) via Takagi-Sugeno (T-S) fuzzy method approach. Based on Lyapunov stability theory, sliding mode control strategy, and T-S fuzzy method, a sliding mode controller is proposed to stabilize the PMSM systems. An illustrative example is provided to(More)
