Fan controller and fan coil unit self-adaptive control system and method

The invention discloses a fan controller and a fan coil unit self-adaptive control system and method.The fan controller comprises a parameter setting unit, a fan coil unit self-adaptive control unit and a fan coil unit self-adaptive control unit, the parameter setting unit inquires a pre-stored parameter form according to a fan coil unit model set by a dial switch so as to call working parameters; the signal conversion unit responds to a gear signal generated by the working gear setting of the temperature controller; the calculation unit is used for selecting corresponding working parameters to calculate target torque according to the gear signal; the working state monitoring unit detects current working state parameters of the fan; the self-adaptive control unit is used for calculating according to the target torque, the working parameters and the current working state parameters to determine self-adaptive working parameters and obtain a target rotating speed; and the fan driving control unit drives the fan
