1.3.2. List and explain the general control rules of system control ?
1. Real-time control: System control should operate in real time to effectively monitor, analyze, and respond to changes in the system. This ensures that the system is constantly optimized and adjusted to meet desired performance levels.
2. Feedback control: Feedback control is essential for system control as it involves measuring the output of the system and comparing it to the desired set point. Any differences are then used to adjust the control inputs to bring the system back to the desired state.
3. Stability control: Ensuring stability in a system means that the system does not oscillate or exhibit erratic behavior. Control rules should be designed to maintain stability by preventing overshoots, oscillations, and instability.
4. Robustness control: System control should be robust to variations in system parameters, disturbances, noise, and other uncertainties. This involves designing control strategies that can adapt to changes in the system and maintain performance under varying conditions.
5. Flexibility control: The control system should be flexible enough to handle changes in the system requirements, operating conditions, and disturbances. This requires the ability to reconfigure control strategies, adjust set points, and adapt to new conditions without compromising system performance.
6. Optimality control: System control should aim to optimize the system performance by minimizing costs, energy consumption, waste, or any other relevant criteria. Control rules should be designed to achieve the desired performance objectives while minimizing resource utilization and maximizing efficiency.
Overall, the general control rules of system control aim to ensure that the system operates efficiently, reliably, and safely by maintaining stability, feedback, real-time operation, flexibility, robustness, and optimality. These rules are essential for effective control of complex systems in various fields, including engineering, economics, healthcare, and many others.
