The invention provides a self-adaptive temperature control method, device and system for magnetic stimulation equipment. The method comprises the following steps: step 1, establishing a physical model of a magnetic stimulation system according to electrical parameters of all electronic components of the magnetic stimulation system and parameters of a coil; 2, establishing a mathematical model according to the physical model, and simplifying the mathematical model to obtain a transfer function of the magnetic stimulation system from the input voltage to the output current; 3, fitting real-time parameter values of the magnetic stimulation system at the moment through a least square method according to real-time input voltage and output current of the magnetic stimulation system and the transfer function; 4, obtaining the real-time temperature of the coil according to the real-time parameter value; 5, calculating the temperature error between the real-time temperature of the coil and the preset temperature of th
