An electrical command signal to a direct drive valve is compensated by a digital signal processor to cause the output hydraulic fluid flow from the valve to conform to a desired predetermined flow. The compensation is accomplished by measuring flow from the valve using a standard direct drive valve code. This flow is compared to a desired flow and the difference is taken on a point to point basis. A compensation is then calculated to change the command signal so as to cause the flow to be according to the desired flow.
