The system we will be employing in this activity is a simple electrical circuit consisting of a resistor R and a capacitor. Simulink Tutorial ExamplesC in series. The Arduino board will be used for generating the input to this RC circuit and for measuring the output of. Specifically, the input to the circuit will be a 5 Volt step, generated from one of the boards Digital Outputs, applied across the resistor and capacitor. The output of the circuit will be the voltage across the capacitor which will. Analog Inputs. This data is then fed to Simulink for visualization and for comparison to our resulting simulation model output. Purpose. The purpose of this activity is to demonstrate how to model a simple electrical system. Specifically, a first principles approach. The associated. experiment is employed to demonstrate the blackbox approach, as well as to demonstrate the accuracy of the resulting models. This activity also provides a physical example of the common class of first order systems. Modeling from first principles. First we will employ our understanding of the underlying physics of the RC circuit to derive the structure of the system model.

Resolvers and synchros are transducers that convert the angular position andor velocity of a rotating shaft to an electrical signal. Both deliver signals. Id=62009828001&videoId=3521166043001' alt='Arduino Simulink Tutorial' title='Arduino Simulink Tutorial' />To begin, we assume a direction for the current and then apply Kirchhoffs Voltage Law loop law. Current flows from a higher potential to a lower potential, therefore, the direction of the current will be clockwise. The loop law states that the sum of voltages around a closed loop must equal zero. Thus, the loop law produces the following. An alternative to the intregro differential equation model of a dynamic system is the transfer function. The transfer function captures the inputoutput behavior of a system and is derived by first taking the Laplace transform. Next we must perform some algebra to re arrange the above into the form of its output divided by its input. In this case. our input is and our output is. Therefore, we must eliminate the current from the above since it is neither an input nor an output, and we must introduce the output into the above equation. Solving the above equation for we arrive at the following. Then we can recognize that the output voltage across the capacitor is. Taking the Laplace transform and again solving for, we arrive at the following. Setting the two previous equations equal to one another, we can eliminate. Then re arranging into the desired form of output divided by input, we produce the resulting transfer function model. Recognizing the above as a first order system, we can manipulate the transfer function so that it has the standard form shown. In this form we can see by inspection how the parameters of the circuit affect its response. Specifically, the values of the. Windows Driver Ftdi Cdm. The circuit components, however, cannot influence the circuits steady state performance as indicated by the fact that the. DC gain always equals 1. System identification experiment. In this experiment we will record the output voltage of the RC circuit for a step in input voltage. Based on the resulting. This approach is sometimes referred to as blackbox modeling. After we have generated such a model, we will compare it to the first principles derived model we. Hardware setup. Our simple RC circuit can be implemented on a breadboard and connected to the Arduino board as shown. One thing to note is. Specifically, if your capacitor has legs of different. Orient an electrolytic capacitor. The. Arduino board is employed to receive the input command from Simulink and to apply the input voltage to the circuit via a. Digital Output. The board also acquires the output voltage data from the circuit via an Analog Input and communicates the. Simulink. In this experiment, the values of the resistor and capacitor are chosen such that the circuits time response is slow enough. ArduinoSimulink setup can sample the circuit at a fast enough rate to give a clear picture of the circuits output. If the sampling rate is at least 1. In this experiment, we chose and to produce a circuit with time constant second. This is a low power application so most resistors and capacitors available will work fine, just make sure that the. Volts. Software setup. In this experiment, we will employ Simulink to read the data from the board and to plot the data in real time. In particular. we will employ the IO package from the Math. Works. For details on how to use the IO package, refer to the following link. The Simulink model we will use is shown below and can be downloaded here, where you may need to change the port to which the Arduino board is connected the port is COM5 in this case. As shown below, the input voltage command is generated by a Pulse Generator block. This block is chosen because of its generality. Step block. The Pulse Generator block generates values of 0 or 1 which are. Arduino Digital Write block. Since we are using channel 8 for the digital output, we double click on the Arduino. Digital Write block to set the Pin to 8 from the drop down menu. An input of 0 to the Digital Write block causes an output of 0 Volts to be generated at the corresponding. Digital Write block generates an output of 5 Volts. This scaling is captured by the Gain block. Scope block. In this model the Pulse Generator block is set to output 0 for the first 5 seconds. The Arduino Analog Read block reads the output voltage data via the Analog Input A0 on the board. Double clicking on the block. Pin to 0 from the drop down menu. We also will set the Sample Time to 0. This is 1. 0 times faster than the circuits time constant and hence is sufficiently fast. The other blocks in the. Sample Time of 0. In the downloadable model, the sample time is set to the variable Ts which needs to be defined in the MATLAB workspace by typing Ts 0. The Gain block on the Analog Input is included to convert the data into units of Volts by multiplying. This conversion can be understood by recognizing that the Arduino Board employs a 1. Analog Input channel reads a voltage between 0 and 5 V and slices that range. Therefore, 0 corresponds to 0 V and 1. V. The given Simulink model then plots the commanded input voltage and recorded output voltage on a scope and also writes the. MATLAB workspace for further analysis. The Arduino Digital Write block, the Arduino Analog. Read block, the Arduino IO Setup block, and the Real Time Pacer block are all part of the IO package. The remaining blocks. Simulink library, specifically, they can be found under the Math, Sources, and Sinks libraries. Once the Simulink model has been created, it can then be run to collect the input voltage and output voltage data. Executing. the following code at the MATLAB command line will generate the graph shown below. Note that we plot only the last five seconds. Volts. titleRC Circuit Step Response. Location,South. East.
