Basic Simulation Examples of ADRC (Active Disturbance Rejection Control)

This program implements simulations of fundamental ADRC examples and illustrates the key advantages and benefits of Active Disturbance Rejection Control. ADRC (Active Disturbance Rejection Control) represents an advanced control technique that offers significant improvements over traditional PID control. For instance, ADRC effectively suppresses various system disturbances through its unique observer structure - typically implemented using Extended State Observer (ESO) algorithms that estimate and compensate for total disturbances in real-time. This approach provides enhanced robustness and adaptability to dynamic system changes. Furthermore, ADRC handles nonlinear system characteristics effectively through its nonlinear feedback control law, often implemented using tracking differentiators (TD) and nonlinear state error feedback (NLSEF) components. These features collectively improve control precision and system stability. Consequently, ADRC has gained widespread adoption in industrial control applications and is increasingly becoming a mainstream control technology in modern industrial automation systems. The simulation code typically includes modules for ESO implementation, disturbance compensation logic, and controller parameter tuning demonstrations.
