Abstract Steady‐state simulation (Aspen, PRO/II, WinGEMS, CADSIM Plus) guides equipment selection, operating conditions, and optimization to design chemical processes like Kraft pulping, specialty chemicals, petrochemical complexes. Ensuring that the characterizes yields, heat transfer loads, purity, utilities demand, profitability requires data represents physicochemical transport properties of each stream unit operation. Here, we present strategies validate steady‐state simulations against plant expectations from operators. To build real‐time data, but errors contaminate measurements dynamic conditions—start‐up, shut‐downs, process upsets—compromise fidelity. A pre‐treatment step removes incongruous on conditions representative steady‐state. Working through with experts (informal validation) comparing results (formal reduces gross error an objective achieve a accuracy within one standard deviation measurement variability. bibliometric review highlights limited focus validation in field engineering.

ABSTRACT Magnetic Levitation (Maglev) is a technique that involves suspending an object using magnetic field. This study presents novel approach for robotic arm joints and end effectors by utilizing the functioning prototype of Maglev system due to their similar functionality. The proposed utilizes fractional‐order enhanced model reference adaptive controller (FOEMRAC) in conjunction with Coyote optimization algorithm (COA) control stability levitating objects. FOEMRAC employs modified MIT rule as its adaptation mechanism. simulation performed Quanser system, comparison done other state‐of‐the‐art techniques such linear quadratic regulator (LQR), particle swarm optimization‐LQR (PSO‐LQR), LQR + proportional integral (LQR PI), derivative PID), voltage PI (PIV (EMRAC), FOEMRAC, PSO‐FOEMRAC, respectively. robustness controllers assessed various error criteria, absolute (IAE), square (ISE), time (ITAE), Additionally, rise time, settling overshoot, undershoot have been employed purposes load disturbance parametric uncertainties. results are also validated on real‐time hardware, demonstrating superior performance COA‐FOEMRAC compared controllers.

Abstract Control strategies designed for step signals fail when applied ramp tracking and disturbance rejection. Hence, this work presents a novel dual-loop control technique rejection in unstable systems. To begin with, first the process is stabilized using proportional-derivative (PD) compensator (in internal loop). This PD was created utilising direct synthesis approach. Using loop shaping approach, proportional-integral-derivative controller outer-loop) then developed to integrate stabilised plant dynamics. Simulations are done standard CSTR (Continuous Stirred Tank Reactor) models by applying step/ramp reference disturbances. The proposed strategy shows satisfactory servo regulatory response than existing designs while dealing with types of signals. Lastly, performance summary also presented on different errors.
