DC Servo Control Trainer

The GSMT series DC servo control experiment platform provides the basic experiment device for elementary control and automation courses in electronic and computer engineering, mechanical engineering. Various experiments such as system identification, modeling of DC servo motor, controller design and controller performance analysis etc. can be performed. With this platform, users can understand the basic principles of PID's influence on system performance index, master the method to adjust the PID current controller, speed controller and position controller parameters of the DC servo motor and comprehend the influence of damping torque and disturbing torque on position and speed control performance, so as to learn the practical skills of the motion control. The series contains GSMT2012, the system of intelligent servo drive-based single motor; and GSMT2014, the system of twin motors based on high-performance motion controller GT-400 developed by Googoltech and the intelligent servo drive, which enables the real time control experiment under MATLAB/Simulink, and covers system modeling and stability analysis, time-domain analysis of second-order system, root locus analysis of third-order system, frequency-response analysis, PID calibration, root locus correction, frequency domain method correction and state feedback. By contrasting different control methods, one can better understand the control theories and learn their applications. In addition, Googoltech also provides controller free DC servo experiment platform GSMT2004 that allow users to integrate the self-developed controller or third party controllers flexibly. The model GSMT2004 come with sensors of DC servo motor, encoder, speed measuring motor, rectilinear potentiometer.
