Department of Chemical Engineering University of California, Santa Barbara ChE 152B Winter, 2010 Lab 3: Decoupling Control 1. Introduction In this lab you will design and evaluate several types of decoupling control strategies for the 4-Tank System. Two control strategies from Chapter 18 of the textbook will be considered: a. Static decoupling b. Partial (one-way) dynamic decoupling to improve h 1 control. 2. Pre-lab Analysis Prior to Lab 3 you should select the best multiloop PI control settings based on the results from Lab 2. For each of the two decoupling design methods of Section 1, design the decouplers based on a transfer function model. The design objective for the partial decoupler is to improve the control of liquid level h 1 . If a theoretical decoupler is not physically realizable, suggest an appropriate approximation that can be implemented. 3. Experimental Activities Important: Be sure to record all transient responses and other relevant information, such as controller settings and bypass valve positions. Also, back-up your
