Pneumatic control valves are frequently used in industrial facilities to regulate fluid flow rates precisely. These valves often introduce unexpected dynamics into the control loop because of the characteristics of their inputs and outputs. The control loop’s performance suffers as a result, which is undesirable. In this inquiry, a fractional order parallel flow control system that is both reliable and strong is proposed (FOPCS). It is a variation of the parallel control structure (PCS), known as a fractional order parallel control structure (FOPCS), that uses fractional order calculus to increase control-loop resiliency while maintaining efficiency. To fine-tune the control structure’s parameters, researchers used a backtracking search strategy. Because of this, the control loop’s efficiency went through the roof. FOPCS has been proven to be a success through extensive laboratory-scale studies using modern data collection methods. Over a long period of time, these experiments were conducted. The suggested FOPCS is analysed in terms of servo, regulation, and robustness to see how well it works. FOPCS and PCS are compared quantitatively using the absolute error, controller output rate, and the combined algebraic total. FOPCS was able to manage the unexpected and nonlinear behaviour of pneumatic control valves in the flow control loop, according to all of the experimental tests.
