Improving Performance Of An Energy Efficient Hydraulic Circuit Tonglin Shang by Tonglin Shang instant download after payment.

A pump-controlled hydraulic motor system was used as the basis of the study
because of its high circuit efficiency. This is primarily because there is no power loss
between the pump and motor. To improve the dynamic response of the pump, a DC motor
was designed to control the pump swashplate (and hence flow rate) directly. The pump and
DC motor were mathematically modeled and their parameters were experimentally
identified. Based on the model and experimental results, a nonlinear PID controller was
designed for the DC motor. By means of the DC motor’s quick dynamic response (in the
order of 10 ms), the DC motor controlled pump demonstrated a fast dynamic response
with a rise time of 15 to 35 ms depending on the pump pressure.
