【Abstract】 The principle of thermodynamic performance test and the test-bed system of radiators as well as the principle of PID control are introduced. According to the requirements of test standard, the system is equipped with PID controllers, the auto-adjusting procedure for PID parameters is set, and the system adjusting procedure is analyzed. After the practical measurement, the system is proved to meet the requirements of test standard entirely.更多还原
