Source measure unit (SMU) is a comprehensive instrument that provides functions such as measuring and supplying voltage and current sources. As the electronics research industry increases its requirements for product measurement and power supply, there is an urgent demand for better performance of the SMU control system. Based on the high cost and difficulty of entity optimization, this paper proposes the utilization of circuit analysis and Simulink to model and simulate the control system. Based on the foundation of PID control, the role of each control link is discussed in this paper. The simulation results show that PID control module can effectively optimize the performance of the SMU transient response by adjusting PID parameters under the input disturbance. On the basis of Simulink model, it is more convenient to improve the SMU and obtain a stable signal for the device under test, so that the SMU can better serve the electrical test field.
