Implementing virtually

The detailed procedure to perform a virtual experiment is explained in Chapter. A summary of the same is provided in section 1.1. It is same for this section with following changes.

1. Step1: The working directory is pid_controller. Open this directory.
2. Step2: Same
3. Step3: Same
4. Step4: Switch to the PID controller experiment directory and double-click on the file pid_ta_bda_virtual.sce. This will launch scilab and also open the file pid_ta_bda_virtual.sce in the scilab editor. Linux users will have to launch scilab manually. They also have to change the working directory to pid_controller and then open the pid_ta_bda_virtual.sce file in the scilab editor.
5. Step5: Same
6. Step6: Execute the file pid_ta_bda_virtual.sce. Expect the PI controller xcos diagram to open automatically. If this doesnt happen, check the scilab console for error message.
7. Step7: Execute the PI controller xcos diagram.
8. Step8: Same

Due to the introduction of derivative action, control effort shows lots of fluctuations. By using filtered form of PID, we can make derivative mode implementable.
