Fpga Implementation of low Power Multi Channel Generalized Pid Controller Frame Work for Industrial Automation Applications

M. Srujana, Shaik. Saidulu

Abstract :

Proportional–Integral–Derivative (PID) controllers are universal control structure and have widely used in automation systems, they are usually implemented either in hardware using analog components or in software using Computer–based systems. In this work, we focused our works on building a multi–channel PID controller by Field Programmable Gate Arrays (FPGAs). Combining FPGA with high speed multi–channel serial ADC and serial DAC, the designed system has the effects of fast speed, high accuracy, compact size and cost effectiveness. To overcome the hardware complexity by the use of more processors for multi channel, we are using single pid controller for multi channel .Multi channel can be implemented by the use of FPGA.when the error is more it can DIFFERENTIATE and produce the constant output, when signal is low when compared to reference signal it can INTEGRATE it.FPGA can offer parallel processing, more speed.
