Final answer:
Closed-loop control systems are actually less sensitive to parameter variations because they incorporate negative feedback loops that help maintain stability by correcting deviations. In contrast, open-loop systems do not have this capability and are more susceptible to changes in parameters. Both negative and positive feedback mechanisms are essential in different contexts, such as in biological systems and plant biology.
Step-by-step explanation:
The statement that closed-loop control systems are more sensitive to parameter variations than open-loop control systems is false. Closed-loop systems, also known as feedback control systems, are designed with a negative feedback loop mechanism that helps to correct the system's output by reducing discrepancies between the desired and actual performance. This control mechanism serves to reduce an excessive response and keep a variable within its normal range, thus making them less sensitive to parameter variations compared to open-loop systems, which do not adjust based on the output and are therefore more sensitive to changes in parameters.
Real-world examples of closed and open systems include various mechanisms and processes. For instance, biological systems often utilize negative feedback mechanisms, like those seen in homeostasis, where the system responds to changes by initiating processes that counteract further change. On the other hand, positive feedback loops, which are less common, serve to intensify a response until an endpoint is reached, such as in blood clotting and childbirth.
In the context of plant biology, it's noted that plants use both negative and positive feedback mechanisms to maintain their internal environments and respond to external environmental changes. Moreover, simulation models are often employed to address complex systems, particularly linear systems that are mathematically intricate.
