Description
Summary:•A model obtained by recently proposed closed-loop process fast identification.•Design parallel PID controller using Particle Swarm Optimization with constraints.•Evaluate performance of parallel PID controller, with a higher-order noise filter.•Proposed closed-loop analysis performed by using the model of process.•Verification of proposed closed-loop analysis on laboratory thermal plant, with noisy measurements. A model, obtained by recently proposed closed-loop process fast identification, is used to design and evaluate performance of parallel PID controller, with a higher-order noise filter, by applying constrained optimization and simulation with estimated band-limited white noise added to controlled variable. On a laboratory thermal plant, with noisy measurements, it is demonstrated that the proposed closed-loop analysis performed by using the model is confirmable on the plant.
