I would also like to thank Hannu Lehmuskuja for pointing out an error related to the delay. I would like to thank Torcuato for pointing out the error. Torcuato Fernandez pointed out an error in original version, which has since has been corrected.
#FREE EXCEL DOWNLOAD PIRATE SIMULATOR#
The PID Simulator tool has been the most downloaded tool on this site and I am grateful to the users who sent me a lot of positive feedback about it.
The equation implemented is:Į = Controller error = Set Point - Process Value The tool simulates the parallel form of the PID equation, this is form that is widely used in academic environments. This tool can be used to study the effect of various controller parameters on the closed loop behaviour and to study techniques such as Ziegler Nichols method of controller tuning. Choose the “Closed Loop” option to view the closed loop response on the chart. These parameters are the controller gain, integral time and the derivate time. To simulate the closed loop response, key the controller parameters into the “Controller” box. The Manipulated Value is plotted on the secondary axis. In this mode, the controller is not used. Details of these parameters are givenĬhoose the “Open Loop” option and the loop drawing changes to the open loop configuration. The First Order Time Delay (FOTPD) process has 3 parameters – Process Gain, Lag Time and Delay Time. xlsx file (92 KB)Įnter the process parameters into the “Process” box. This is a great tool for learning the basics of PID control and loop tuning. Both open and closed loop processes can be simulated using this powerful tool. The PID Loop Simulator is an Excel tool to simulate a Proportional, Integral and Derivative (PID) controller on a First Order Time Delay (FOTPD) process.
