Speed-adjustable steepest tracking filtering method and device

The invention provides a speed-adjustable steepest tracking filtering method, device and equipment and a storage medium. The method comprises the steps that an input signal is input into a first subtractor to obtain feedback output; inputting the feedback output into a first integrator to obtain first integral output; inputting the first integral output into a second integrator to obtain second integral output; inputting the second integral output into a first subtracter to form closed-loop feedback; inputting the second integral output and the output of the first delayer into a first summator, and inputting the first addition output into a second subtracter after passing through a fixed proportion controller; and inputting the first integral output and the output of the second delayer into a second adder, and inputting the second addition output into a second subtracter after passing through an adjustable proportional controller to obtain an adjustable-rate steepest tracking filtering output signal output by
