Air conditioning optimization control method and system for railway station

The invention relates to the technical field of railway station air conditioning, in particular to an air conditioning optimization control method and system for a railway station, and the method comprises the steps: setting characteristic parameters, a control target, an optimization target and constraint conditions of a tall and large space air conditioning control system; reading and calculating parameters influencing a control target and parameters of the control target; future state parameters of the air conditioning system are estimated, future output of the system is predicted, and control quantity is optimized, solved and calculated according to a control target, an optimization target and constraint conditions; and outputting the obtained optimal control value to an actuator. According to the scheme, multi-channel parameter control output is provided, a tall and large space air conditioning control algorithm with constraint conditions and optimization strategies is achieved, an existing railway stati
