With the availability of microcomputers it is now possible to design low cost digital controllers. In the present work the design of a microprocessor based real time digital controller is presented. The microcomputer used was an 8080 based PROMPT 80. The necessary hardware to interface this computer with a 'plant' was designed and tested. The software for the controller was written such that it can be operated In Proportional, Proportional-Integral and Proportional-Integral-Difference modes. With minor changes in the programs the controller can be operated in Integral, Integral-Difference and Proportional-Difference modes. The. necessary modifications are indicated. The controller performance was tested using a second order plant simulator. The results obtained were compared with the calculated values and it was found that the controller wa° performing as expected. A complete listing of programs and instructions to operate the controller are given*.
