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 first 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 second setpoint to the first setpoint, reading and recalling the optimized command signal associated with the first setpoint from the memory, and transmitting the recalled optimized command signal from the memory to the pump.
