Understanding Open Loop Control Systems
Open loop control systems are characterized by their operational independence from the output. This means that the control action is not influenced by the output signal, which distinguishes them from closed loop systems.
Key Features of Open Loop Control Systems:
- Independence from Output:
- In an open loop system, the control action is determined solely by the input signal and does not adjust based on the output signal's actual performance. This lack of feedback means that the system does not correct itself if the output deviates from the desired result.
- No Error Detection:
- Unlike closed loop systems, open loop systems do not have an error detector to measure the difference between the desired output and the actual output. Thus, they cannot make real-time adjustments.
- Control Action Based on Input:
- The system relies on predetermined inputs to generate a control action. For example, a washing machine set to a specific cycle will operate based on that cycle's parameters without considering the cleanliness of the clothes.
Examples of Open Loop Control Systems:
- Electric Fans:
- A fan operates at a set speed regardless of the room temperature or airflow.
- Toasters:
- A toaster heats bread for a fixed duration, irrespective of the desired toastiness.
Conclusion:
In summary, the correct answer to the question is option 'C'—the control action in open loop systems is indeed independent of the desired output signal. This trait leads to simplicity in design and operation but also limits the system's adaptability and accuracy.

- In open loop control systems, the control action is independent of the desired output signal.
- The system operates without feedback, meaning it doesn't compare the output with the desired value.
- Control actions are predefined and do not adjust based on output changes.
- This can lead to inaccuracies if the system or external conditions change.
- Open loop systems are typically simpler but less accurate compared to closed loop systems, where feedback adjusts the control action.
