MATLAB CONTROL SYSTEM DESIGNER TUTORIAL SOFTWARE

To toggle grid, right click on the plot area.В To add or delete zeros or pole or whatever, right click on the plot and choose. Start tuning by moving the small squares. To start tuning, zoom in the pink square in the root locus editor until the square splits up. To open the document, go to FileВ then LoadВ Session. To save your work, go to FileВ then Save Session. Then click OK.ДЄfter clicking OKВ of Figure 10, вЂњSISO Design for SISO Design TaskвЂќ is no longer empty as Figure 11.

The value of G will then become GcВ as Figure 10. Initially the value of G, H, C and F is 1.Д¬lick Browse on Figure 8 and Figure 9 will show.ДЇrom Figure 9 select G on вЂњImport model forвЂќ section. On the вЂњSISO Design for SISO Design TaskвЂќ window, click on FileВ then Import. Below window show up.ДЇ=Input Filter,В C=Compensator,В G=Plant,В H=Sensor/Feedback.В By default, the values of F, C, H and G is 1.В Be sure to select the sign of S1 to вЂ“1 for negative feedback.В Select the upper left most control architecture. On вЂњControl and Estimation Tools ManagerвЂќ, click on the вЂњControl ArchitectureвЂќ to select the architecture type. Take note that the вЂњSISO Design for SISO Design TaskвЂќ is empty this time. On the command window type below and enter. SISO tool is bundle with the control system toolbox. We will design now the controller and to make this easy we will use the SISO tool. On the command window type below and enter.ДҐ.В Loading theВ SISO Tool to Design the ControllerДЇinally we already have an S domain plant transfer function, Gc. In this tutorials we opt to use the S domain of the plant transfer function to prepare a match controller. Transfer function Gd is still in discrete form with a sampling time of 0.001 sec. Once the enter button is pressed this should be displayed in the command window On the command window type below and enter In this tutorials we will consider a single transfer function of the plant by having the two in series. The command window must display like this after encoding the two transfer functions.ДЇigure 3 3. On the command window, type the following and enter: If otherwise, donвЂ™t worry all the commands and syntax are the same although you may need to do a little exploration.ДЇigure 2 is the command window of Matlab R2011a.ДЇigure 2 2. If you are using the same version with me (R2011a), all the instructions are applicable to you. Matlab Control Design Step by Step Tutorials We are going to design a controller to attain our set requirements. The given transfer functions in this tutorials are for the plant. Reference is the set target level for the output to stay with. Most of the times, the gain is set as 1 (direct feedback) for simulation purposes.В SummerВ is the one processing the difference between the reference and the feedback. This is a negative feedback with a particular gain. Feedback is the one getting sample from the output and compare it to the reference. Controller is the one making the output to be within the specifications. Plant is the system to be controlled such as a motor, switching converter, aircraft wing, robotic arm etc. For the benefit of everyone especially to those who do not have idea or already forgotten control system, we will be having a short review.ДЄ control system consists of a plant, compensator or a controller, feedback, reference and a summing element.ДЇigure 1 displays a common control system block diagram. In this article we are going to discuss control system. We will convert also the transfer function of the plant into s domain to pair it with an s domain control as well.

In this article let me combine the two plant transfer functions (series combination) to obtain a single one. The transfer functions are define in the z domain or discrete format. Gd1 and Gd2 are the transfer functions of the plant that we are going to control the response. Phase margin Open Loop = 75Вє +/-3% -Gain margin Open Loop = 24 dB +/-2% -Rise time = 0.5 to 1.5 sec -Settling time = 2.5 sec maximum -Overshoot = 1% maximum These are our objectives in this tutorial:

MATLAB CONTROL SYSTEM DESIGNER TUTORIAL SOFTWARE

You may just need a little exploration but do not worry this software is user friendly. Higher version of matlab has different appearance or interface but the command/syntax are all the same. In this tutorial I use R2011a version of matlab. I am about to share to you matlab control design step by step tutorials. However, we will not having the same experience. Self studying is not easy, it took me sometimes to learn and get what I want. I remember when I started to study matlab I was searching for matlab control design step by step tutorials but I have not seen any.
