Controller transfer function for PID controller is: s P 4 s G (s) 0.75k.P. ' # $$% & + = u (2) Thus the PID controller has a pole at the origin and double zeros at s =-4/P u. The advantage of Z-N method is that it does not require the process model. Table 1- Controller parameters for closed loop Ziegler-Nichols method Controller. Liquid level control of coupled tank system using Fractional PID controller Arun Kumar, Munish Vashishth and Lalit Rai Abstract—In process industries PID controllers are used more. In PID controller we have three parameters for tuning and tuning is done by using Ziegler-Nicholas method. In this paper. Water and/or steam for boiler systems. They are typically engineered with very tight tolerances around set point in order to maintain a specific level of steam production. Variation of the level is detrimental to the process’ efficiency and productivity. The PID Controller and Control Objective. Feb 28, 2017  Tuning a PID Controller is important for Heat treatment processes to demonstrate the need for proportional-integral-derivative (PID) control. To guarantee consistent product quality, the. How to Automate Tuning of PID Controller. Most PID controllers sold today incorporate auto-tuning functions. Operating details vary between manufacturers, but all follow rules where the controller “learns” how the process responds to a disturbance or change in set point and calculates appropriate PID settings.

Part 1: Building and Simulating a Simple Simulink Model Learn how to get started with Simulink. Explore the Simulink start page and learn how to use some of the basic blocks and modeling components.

Part 2: Adding a Controller and Plant to the Simulink Model Explore how to create a plant control model using Simulink. The example walks you through how to create both open- and closed-loop systems.

Part 3: Viewing Simulation Results Visualize simulation results using tools such as the Simulation Data Inspector to view and compare signal data from multiple simulations, or the Dashboard Scope to see your results directly in the Simulink editor.

Part 4: Tuning a PID Controller Automatically tune PID gain values using the PID controller block and instantly see the results of your changes in Simulink.

Part 5: Comparing and Saving Simulation Data Use the Simulation Data Inspector in Simulink to compare the results of multiple simulation runs. Open the results in MATLAB Figures to further annotate and add information to your figures.

Part 6: Managing Your Simulink Model Use Simulink Projects to manage all the models and documents related to your project. Easily track and work with your files, and allow team members to access all documents.

Part 7: Adding Components to Your Simulink Model Create subsystems and components in your Simulink model. Create model references so you or your team can work on components independently from the top-level model.

Part 8: Modeling Continuous and Discrete Systems in One Simulink Model Switch between continuous and discrete domains. This example shows how to update a Simulink PID controller block in order to easily move between the two domains.

Part 9: Using Templates and Examples Save and share your model as a template so team members can access it right from the Simulink start page. In addition, explore examples that help get you started with models for many applications.
