  • “Introduction to Real-time Control System Based on xPC Target” — major elective course

Teacher: Qiquan Quan
Teaching Object: B4 students majoring in aerospace manufacturing engineering

In view of the current undergraduate training mode of the Institute of electrical and mechanical, which focuses too much on mechanical knowledge, combined with some experience in my own research work, the course “Introduction to Real-time Control System Based on xPC Target” was opened for senior undergraduates in the fall semester of 2014. MATLAB, which is internationally popular in engineering colleges, is introduced into the course, focusing on how to realize system simulation of hardware in the loop (HIL) and product Rapid Prototyping Control (RPC) based on xPC Target, and construct real-time control electromechanical system. The purpose is to train undergraduate students to form the design concept of mechatronics and improve their comprehensive design ability of electromechanical system. At present, there is no comprehensive introduction of xPC Target’s Chinese textbooks in China, let alone the corresponding experimental teaching instruments. A portable real-time servo control mechatronics system is developed to serve the classroom teaching and experimental teaching of this course.

XPC Target is an additional product provided and released by MathWorks, Inc., based on real-time Workshop. It can transform the ordinary PC into a real-time system, supporting a variety of Types of I/O device boards, and is a PC solution for product prototype development, testing and configuration of real-time systems. As an important tool in the field of system dynamic simulation, xPC Target is an excellent choice for system semi-physical simulation. XPC Target adopts the host-target mode of “two-machine”. The host is used to run the Simulink module and create the target application. The target machine is used to execute the code generated by the host machine and send control signals to the mechanical system and receive feedback signals through the I/O board. XPC Target achieves communication between host and target through Ethernet connection or serial port communication.

a) Mechanical and electrical system hardware construction experiment

Students complete the construction of the electromechanical system by connecting the cables between the servo motor – driver – terminal station, displacement sensor – terminal station, travel switch – terminal station, temperature sensor – terminal station. This experiment course can improve students’ understanding of the basic components of the electromechanical integration system and deepen students’ understanding of the connection relationship between the components of the electromechanical system.

b) Electromechanical system software development experiment

Students write the real-time control program in the host Simulink environment to realize the motion control of servo motor and the signal acquisition of displacement sensor, temperature sensor and travel switch in the system. This experiment course enables students to deeply learn the writing method of electromechanical system control software program and master the method of sending and collecting typical analog signals and digital signals in electromechanical system based on xPC Target.

c) Servo motor control mode comparison experiment

Students write the real-time control program on the host to realize the motion control of the servo motor’s torque mode, speed mode and position mode respectively, and compare and analyze the output characteristics of the servo motor under different control modes. This experiment course can enable students to realize different working modes of servo motor based on xPC Target, and deepen students’ understanding of output characteristics of servo motor under different working modes.
