  • Publication number: 20250136407
    Abstract: The present disclosure discloses a method for collaboratively controlling a multi-channel braking system of a mine hoist, including obtaining the abrasion loss of the brake shoe by detecting position information of the brake shoe of each of disc brakes in real time, dividing abrasion loss levels by determining different abrasion degrees of the brake shoe, formulating three braking force distributing modes: an average distribution, a proportional distribution, and an index distribution according to the abrasion loss levels, thereby dynamically adjusting a set braking pressure of each of the disc brakes, tracking and controlling the set braking pressure through the disc brakes by adopting a pressure closed-loop control method by utilizing a pressure signal feedback from an oil pressure sensor, implementing a collaborative braking control of the multi-channel braking system of the mine hoist based on the abrasion loss of the brake shoe.

  • Patent number: 12266942
    Abstract: A fast-response photovoltaic (PV) simulator based on an improved deadbeat predictive current control (DPCC). Compared to actual PV modules, there is a response time at the output of the PV simulation. Currently widely used PV simulation have a long response time, which cannot meet the performance testing requirements of high-performance grid-connected PV inverters. Based on the energy balance of the inductor during the absorption and dissipation phases, the current control law of the output inductor in the PV simulation was studied in a single switching period, thereby establishing the required DPCC model. An integral compensation eliminates the steady-state error in current tracking caused by nonlinear factors such as time delay and mismatched parameters, enabling its wide application in engineering. For the proposed PV simulator, the transient response time can be reduced to 1.1 ms and significantly shorter than widely used PV simulation.
