Unipolar deviation control algorithm and its application in mine hoist mechanical braking system

A kind of unipolar deviation control algorithm was proposed and applied to mine hoist mechanical braking system. The algorithm can change a feedback control system from no error system to error system, which is beneficial to improve system stability and simplify system design; it can improve system dynamic property without changing system structure. In mine hoist mechanical brake system, the algorithm can be achieved by changing preset form, and was simple and practical.
