The application discloses a kind of hybrid special transmission slip start control method, belongs to hybrid electric vehicle transmission system control technical field.Method as follows: control unit gathers vehicle operating parameter to carry out driving condition classification and slip control state judgment;The target torque of driving motor is reduced to the torque value corresponding to slip speed point;Control the pressure of gear clutch and drop from fully combined state to the slip pressure point matched with current actual transmission torque;Driving motor is switched from torque control mode to speed control mode;Enter multi-power source combined driving state, real-time adjust the slip pressure of gear clutch, execute closed-loop slip control;Slip control exits.The application solves the poor adaptability of clutch slip control and power mode switching in existing hybrid power system, effectively suppresses the jitter and jerk in slip process, balances the power performance and ride comfort of vehicle starting, and can quickly promote the system to enter multi-power source combined driving state.

This invention provides an intelligent control method and system for gas flow in a continuous annealing furnace, comprising: collecting and preprocessing key process parameter data during the operation of the continuous annealing furnace; inputting the key process parameter data into a trained gas flow prediction model to predict and output the target gas flow in each zone of the continuous annealing furnace; the gas flow prediction model is constructed by combining a heat transfer physics model and a data-driven AI model; the heat transfer physics model calculates the optimal furnace temperature setpoint based on the target strip temperature, and the data-driven AI model predicts the target gas flow based on the optimal furnace temperature setpoint; the prediction result conforms to physical laws and also learns the complex nonlinear relationship between actual combustion and control through the data-driven model; correcting the target gas flow based on production process parameters; when the difference between the corrected target gas flow and the real-time detected gas flow exceeds a preset threshold, feedback adjustment of the gas flow in each furnace zone is performed based on the actual strip temperature, target temperature, and furnace temperature using a PID control algorithm. This invention enables intelligent control of the gas flow in a continuous annealing furnace.
