The invention discloses a new valve friction compensation method, and belongs to the field of automatic control. The new valve friction compensation method is on the basis of a proportional-integral (PI) controller, a first-order delay system model and a data drive valve module, wherein the data drive valve module is a two-parameter data drive model. The method comprises the following steps: firstly, determining a compensation time to obtain a time-related parameter, and reckoning an ideal working position of a valve; then, switching the PI controller into a manual state, adding a compensation signal into the output end of the PI controller; finally, adding a step signal in a reverse direction to the output end of the PI controller, so that the output of the valve changes into the ideal working position to compensate for the friction of the valve. By the method, the valve with an oscillation phenomenon can be compensated effectively. In a friction compensation process, the valve can only move twice, so that the wear degree of the valve is lightened greatly, and the service life of the valve is prolonged. According to the method, the structure of the current controller is not required to be modified; only the current automatic control mode is switched to the manual control module; the method can be easily implemented in the industrial field.
