PID Control Performance with Disturbance Observer

We present an excellent MATLAB source code implementation that comprehensively demonstrates PID control performance based on a disturbance observer. The source code can be utilized in various control systems, finding widespread applications in industrial automation, robotics, and other domains. The implementation features disturbance estimation algorithms that compensate for external perturbations, enhancing the PID controller's robustness. The code structure includes modular functions for observer design, PID parameter tuning, and real-time performance monitoring. This source code can be further optimized and customized to meet specific control requirements and application scenarios. We believe this implementation will not only help you better understand the fundamental principles of disturbance observer-based PID control but also provide substantial support for your own control system design and development projects. The code demonstrates practical implementation techniques for integrating disturbance observers with conventional PID controllers to achieve improved system stability and disturbance rejection capabilities.
