The aim of this investigation was to study nonuniform corrosion in the vertical direction Q345 steel South China Sea. First, a metal monitoring system designed and applied based on coulometer principle array electrode technology. Then, through testing, weightlessness analysis, electrochemical surface morphology observation, behavior used an offshore wind turbine Zhanjiang Bay Sea studied. results revealed that within first 30 days experiment, electrodes connected by electricity exhibited...
Aiming at the problems of slow response speed and chattering phenomenon in general sliding mode control permanent magnet synchronous motor, a global fast terminal strategy is proposed to improve anti-interference ability system. A load torque Luenberger observer designed, observed value fed back controller motor system order reduce influence external disturbance. experiments platform built verify performance effectiveness observer. The experimental results show that can better observe actual...
In view of the shortcomings existing multimotor synchronous control strategy, a new method mean deviation coupling for system via global fast terminal sliding mode is proposed. Firstly, mathematical model permanent magnet motor (PMSM) under <math xmlns="http://www.w3.org/1998/Math/MathML" id="M1"> <mi>d</mi> </math> - id="M2"> <mi>q</mi> reference frame established. Next, based on control, calculated by average speed, and structure strategy optimized. The speed controller designed (GFTSMC)...
