Heat pump systems and methods of operating including a first unit having a first unit heat exchanger, a compressor, an accumulator, and a first unit expansion valve, a second unit fluidly connected to the first unit by piping, the second unit having a second unit heat exchanger, and a system controller, the system controller having (I) a PID control element receiving as inputs (i) gain scheduling, (ii) an error signal, and (iii) feedback relating to an opening command of the first unit expansion valve, and (II) a feedforward control element generating a feedforward term that is combined with an output of the PID control element to generate the opening command of the first unit expansion valve. The system controller controls an opening of the first unit expansion valve using the opening command of the first unit expansion valve.
