Fuzzy Controlled Energy Saving Solution for Large-Scale ...

Ask for a quote

Belt conveyors generally run at designed nominal speed. When material loading rate is smaller than the nominal conveying capacity the belt is under the situation of being partially filled. It provides the potential of reducing energy consumption by means of adjusting the speed of the belt. For practical reasons discrete control is preferred to adjust the belt speed.

2018-5-9 · Belt drive systems provide freedom to position the motor relative to the load and this phenomenon enables reduction of the conveyor inertia. It also facilitates quick response when employed in robotics applications. Unfortunately, the flexible dynamics deteriorates the positioning accuracy. Therefore, there exists a trade-off between the simplicity of the control strategy to reject time ...
