In process control, what is typically the first step before implementing a control strategy?

In process control, setting objectives and requirements is indeed a critical first step before implementing any control strategy. This phase involves clearly defining what needs to be achieved with the control system. It ensures that the goals of the process are aligned with the desired outcomes, such as maintaining specific temperatures, pressures, or flow rates. By establishing these objectives upfront, technicians and engineers can tailor their control strategies to meet specific operational criteria and performance expectations.

This foundational step allows for informed decision-making throughout the design and implementation phases. It helps in determining the appropriate type of control system (like PID control, feedforward control, etc.), identifying key performance indicators, and outlining any constraints or limitations of the process. All subsequent actions, including documentation, data analysis, and equipment testing, should be guided by the objectives and requirements established during this initial phase, ensuring that the control strategy developed is relevant and effective.
