real-time systems are loosely defined as the class of computer systems that interact with the external world in a time frame defined by the external world. It is an environment where a single computer is a host and a target. After creating a model and simulating it with simulink in normal mode we can generate executable codes with realtime workshop. Here we have used matlab as an application tool which provide us the specialized tool boxes for specific areas. The realtime window target communicates with the executable program acting as a control program and interfaces with the hardware device through the I/O port. Here we tried to analyse a magnetic levitation system. The control goal is to suspend a steel sphere by means of a magnetic field counteracting the force of gravity and to be able to apply a controlled disturbance to force the sphere to follow a predetermined trajectory. The control to be applied is the voltage, which is converted into a current via internal circuitry in the controller located in the mechanical unit. The current passes through and an electromagnet which creates a magnetic field in its vicinity. The sphere is placed along the vertical axis of the electromagnet after the control system is started in the software. In this way a approach towards realtime workshop is analysed and applied.
