Unformatted text preview: such that the closed loop dominant time constant is around ( τ r =10); (e) Assume the process initially rest at h s = 0.8 m, simulate the closed loop control system performance for ∆h s = 0.2 m at t=0 min (step input of 0.2m from 0.8 m to 1.0 m) ∆h s = 0.5 m at t=100 min (step input of 0.5m from 1.0 m to 1.5 m) ∆h s = − 0.5 m at t=200 min (step input of − 0.5m from 1.5 m to 1.0 m) ∆h s = 0.5 m at t=300 min (step input of − 0.5m from 1.0 m to 0.5 m) ∆h s =0.5 m at t=400 min (step input of 0.5m from 0.5 m back to 1.0 m) Comments on the performance of each design scheme. Note: 1. During the simulation, you may schedule the controllers based on the desired setpoint level in part (b) of the model scheduling method. 2. You must use the original nonlinear model as the process during the simulation....
