1. A method, comprising: obtaining a first setpoint with a computer, the first setpoint being a desired flow rate from a pump; transmitting a first command signal corresponding to the first setpoint from the computer to the pump; measuring a flow rate of the pump and transmitting a corresponding measurement signal to the computer; determining an optimized command signal associated with the first setpoint with a process control system, the process control system configured to incorporate at least the first setpoint and the measurement signal to produce the optimized command signal; storing the optimized command signal in a memory of the computer; changing the setpoint to a second setpoint, the second setpoint being a desired flow rate from the pump; transmitting a second command signal corresponding to the second setpoint from the computer to the pump; and, changing the setpoint to the first setpoint and reading the optimized command signal associated with the first setpoint from the memory and transmitting the optimized command signal to the pump.
