Plantwide/advanced control shortcourse. DAY 1. 1. Overview of plantwide control 2. Selection of controlled variables based on economic : The link between the optimization (RTO) and the control (MPC; PID) layers - Degrees of freedom - Optimization - Many examples VG.exercise 1: Blending-Optimization with quadprog VG-exercise 2: Blending example loss, VG-exercise 3: RGA + PID-Simulation with 1 tank VG-exercise 4: Simulation with 5 tanks and MPC DAY 2 3. Design of the stabilizing control layer ("what more should we control") . 4. Design of supervisory control layer (Decentralized control or MPC?) 5. Where to set the production rate (DAY1) DAY 3 (tuning) 1. Tuning SISO PID loops - tight tuning (IMC rules; effective delay, Skogestad half rule) - smooth tuning (and link to default settings) - Matlab exercises 2. Tuning of cascade controllers 3. Design of decentralized controllers: Sequential and independent design DAY 4 (multivariable systems) 1. RGA analysis 2. Pairing 3. Singular value decomposition 4. RHP-zeros DAY 5 (controllability analysis) 1. SISO pH example - benefits of feedback slugging example - instability combined with RHP-zeros 2. MIMO ---------------------------------- I have a 112 slide "plantwide control" talk that needs to be divided into parts 0. Introduction to plantwide control 1. PID tuning, incl. cascade control and simple loops. Intro to controllability - CONTROL2 With exercises where the students propose tunings and I simulate the results with Simulink Follow book more closely 2. Optimal operation and control (1 h) 3. Selection of controlled variables for optimal operation (1 day) - Alternative methods - Examples 3b. Set production rate and bottleneck - This is related to actice constraint control 4. regulatory control layer - stabilization - what more to control - cascade and time scale separation 5. Advanced/supervisory control (MPC) This is where one normally apply multivariable control, so can go back to Chapter 3 - MIMO transfer functions - Directions is MIMO systems. SVD - RGA - RHP-zeros - Then to ch. 10 on decentrlized control - Examples - Pairing rules - Example - Then back to multivariable control
