یک کنترل کننده PID کلی بر پایه پردازنده های ARM

To design a dedicated Proportional-Integral-Derivative (PID) controller using ARM processor. The embedded PID system is developed using Philips LPC2148 based on ARM7 TDMI-S structure and it is responsible to execute the PID routine. This LPC2148 acquires the process variable through the ADC channel, performs control computations and inturn produces the PWM signal to control the process. This PID controller has been designed to operate in two modes: Auto mode and Manual mode. In Auto mode, the controller parameters are derived automatically. In the manual mode, the controller parameters can be changed manually through increment and decrement switches. This dedicated PID controller can be used in any process applications which needs faster control action.
