| Abstract | ||||
| Motion control system is a system that has a special controller for controlling position, velocity or acceleration. In this paper the position control is concerned. A special application is introduced in detail which is the “gonio-photometer” laboratory which is used to measure the following: a- Luminaire luminous intensity distribution. b- Lamp luminous flux. Position control of this application is concerned having a resolution angle (0.01 degree) with the aid of a dc servo motor system and PID controller in addition to the use of brakes for maintaining better results. Simulation and calculations of the system equations are held using Matlab program. An alternative method is introduced for the position control of the application under study, which is the use of stepper motors instead of dc servo motors. | ||||
