The invention discloses a multi-channel servo control system used for an automobile part fatigue test. The multi-channel servo control system comprises an input circuit, a processor, a PID controller, a comparator, a power amplifying circuit, a servo valve, a hydraulic cylinder, a displacement sensor and a pressure sensor. The PID controller operates a pressure signal received from the pressure sensor and a voltage signal output by the processor to obtain a difference value, a displacement signal detected by the displacement sensor is transmitted to the comparator, the difference value output by the PID controller and the displacement signal detected by the displacement sensor are transmitted to the power amplifying circuit through the comparator, a load is electrically connected with a sensor used for collecting load deformation, a collected signal is transmitted by the sensor used for collecting the load deformation to a PC, a signal conditioning circuit is arranged between the sensor used for collecting the load deformation and the PC, a data collecting card is inserted into the PC, and a front-end port circuit is arranged on the signal conditioning circuit. The aim of improving the disturbance rejection performance, the interconnection performance and the coordination performance of the system is achieved.
Description
Technical field [0001] The invention relates to a multi-channel servo control system for fatigue testing of automobile parts.
