PLC (Programmable Logic Controller) is a commonly used control equipment in industrial automation, which can realize automatic control and monitoring of the production process. With the development of digital industry, PLC virtual simulation technology is becoming an increasingly important part of digital industry, so it has put forward higher and higher requirements for the cultivation of talents in colleges and universities.
In this context, Beijing OBIER has designed an automatic control virtual simulation experiment platform software for the theoretical connection and practical needs of PLC automatic control, modern control and related courses in various universities.
The software includes eight experiments in the automatic control and modern control parts, and focuses on the time domain analysis, frequency domain analysis, time domain correction frequency domain correction in the automatic control, and the establishment of state space expressions, Lyapunov stability animation, state feedback equations, pole configuration, and state observers in the current control, and adds the experimental data and phenomena of the dual-input and dual-output system in the modern control experiments, so that students can more intuitively feel the difference from the single system. At the same time, the model of the robotic arm is used in the software, and according to the data calculation in the background, the robotic arm will move, so as to complete the process of combining virtual and real, so that students can understand the principle more thoroughly in the learning process.
The software can be divided into a dual-end operating system for teachers and students, and teachers can issue and manage the experimental data used by students through fixed systems, custom systems and data management platforms.
Students can conduct simulation experiments of automatic control systems, time domain analysis experiments of control systems (stability analysis), time domain analysis experiments of control systems (dynamic performance analysis), time domain analysis experiments of control systems (steady-state performance analysis), time domain analysis experiments of control systems (influence of open-loop amplification coefficient on stability), frequency domain analysis experiments of control systems, time domain correction experiments of control systems, frequency domain correction experiments of control systems, establishment of condition space mathematical models and system simulation experiments of automatic control systems, Lyapunov stability analysis experiment of the control system, state feedback experiment of the control system (pole configuration of the control system), state feedback experiment of the control system (feedback system with state observer) and other experimental operations.
Beijing OBIER PLC virtual simulation technology cultivates students' engineering practice ability, innovation awareness and problem-solving ability, enhances students' employment competitiveness, helps to cultivate more college talents with engineering practice ability, and plays an important role in college education.
