Abstract :
A ultra-low speed closed loop control system is designed for the isothermal forging technical. Control system applies M/T speed measurement method to improve the speed measurement precision by using the magnetostriction position sensor for position measurement. According to the characteristics of control object, system adopts varying parameter PID control policy to carry out constant speed control and constant shaping-speed control of isothermal forging technical, basing on steady ultra-low speed control. The results show that the control system is able to achieve precision ultra-low speed control and improves the performance of isothermal forging technical, meeting the international advanced standard
