Summary:The invention relates to an independent variable pitch control method for a floating type fan. The independent variable pitch control method for the floating type fan comprises the steps that 1), analyzing a paddle mechanical structure of the floating fan is carried out, a paddle mechanical structure kinetic equation is obtained, 2), an independent variable pitch model is established, 3), a controller ui is designed, and 4), the floating fan is controlled by using the designed controller ui. According to the independent variable pitch control method for the floating type fan, the independent variable pitch model containing disturbance factors is established, the rate function is introduced, the designed controller can track the expected pitch angle in a self-adaptive mode, errors can be converged within limited time, the fan is usually a large-scale time-lag nonlinear system, limited time convergence can enable the fan to quickly respond under complex external conditions, so that the load of the fan is reduce
