AimsOxidative stress is a direct cause of injury in various neural diseases. Manganese porphyrins (MnPs), a large category of superoxide dismutase (SOD) mimics, shown universally to have effects in numerous neural disease models in vivo. Given their complex intracellular redox activities, detailed mechanisms underlying the biomedical efficacies are not fully elucidated. This study sought to investigate...
This paper investigates an estimator-based terminal sliding mode control system. An exact estimator is proposed to exactly estimate the unknown uncertainties in finite time. The output of the exact estimator is used to design a continuous chattering free terminal sliding mode control. The time taken for the closed-loop system to reach zero tracking error is proven to be finite. Experiment results...
This work simulates lateral motion in magnetic levitation (maglev) transportation systems using a novel electromagnetic guidance device. First, current control modules, a pulse-width-modulation (PWM) controller and buck converter, are used for driving electromagnets. The electromagnetic guidance system, which has two current control modules, a gap controller, and a bipolar switching mechanism, controls...
