Lab report for motor control

It is great for beginners who want to make stuff move without building a motor controller with feedback and gear box. Originally used in remote-controlled cars and airplanes. It is controlled by sending PWM signal from microcontroller. The PWM signal tells the servo what position it should move to.

Finally we have observed outputs and discussed differences and similarities between open loop and closed loop control systems. Its operation is very simple, when an input signal directs the control element to respond, an output will be produced.

Examples of the open loop control systems include washing machines, light switches, gas ovens, etc. Closed-Loop Control System The output signal is feedback to the input to produce a new output. A well-designed feedback system can often increase the accuracy of the output.

Figure 2 Sometimes, we may use the output of the control system to adjust the input signal.

This is called feedback. Feedback is a special feature of a closed loop control system.

A closed loop control system compares the output with the expected result or command status, then it takes appropriate control actions to adjust the input signal. Therefore, a closed loop system is always equipped with a sensor, which is used to monitor the output and compare it with the expected result.

Figure 2 shows a simple closed loop system. Differences between open-loop and closed-loop systems Comparing open-loop control with closed-loop control the following differences are seen: Summarising these properties we can define: Systems in which the output quantity has no effect upon the process input quantity are called open-loop control systems.

Systems in which the output has an effect upon the process input quantity in such a manner as to maintain the desired output value are called closed-loop control systems.


Figure 7 Our integrator outputs are shown in the Figure 7. Then, we have observed the output on scope as you seen in Figure 8. Figure 8 Finally we have set simulation duration to 0. Figure 9 Conclusion In summary, we have discussed open-loop and closed-loop control system.

We have learned creating open loop and closed loop control systems and determined differences between the systems.1 ENGS 26 CONTROL THEORY Lab 2: Motor Speed Control Laboratory Equipment and Software Required: Thayer School DC Motor/Tachometer board DTA Data Acquisition Board and PC.

Hello, I'd like to control two brushless servo motors using LabVIEW. I've got a PXI controller card and a Copley amplifier. I've read the Getting Started tutorial but otherwise I am new to LabVIEW.

Speed control methods of DC motor

Speed Control of the DC Motor System Using a PID Controller Fall IMPORTANT: This handout is common for all workbenches. 1. Lab Information Lab Report After the lab, you will work on the problems at the end of the handout on your own and are Begin by connecting the motor control module to the power supply.

The module is marked 5V. TTK Optimization and Control Helicopter Lab Report , Group 1 April 29, The report is organized as follows: Section 2 contains a closer description of the lab setup The rotor thrust is assumed to be proportional to the voltage applied to the motor.

This is a simpli cation.

Generally, rotor angular velocity is. Lab Squirrel-Cage Induction Motor Objectives and Overview • attempt to control the motor speed by adjusting the source voltage; • demonstrate the motor control using Variable Frequency Drive (VFD). your Lab Report (as many entries as you can).

Note that since this motor . Hi FSK. Thanks for using the discussion forums! Motor control is a common application using LabVIEW and you can develop custom functionality such as you are describing.
