Abstract :
Control arithmetic is the key part of monitoring system because it is difficult to formulate exact mathematical model due to nonlinear and time-varying characteristic of construction machinery. In order to improve the running efficiency, a fuzzy PID controller is designed and realized in the monitoring system based on ARM. Besides, three encapsulation functions are designed to carry out data transfer between ARM and Matlab by UART series communication. And then, the fuzzy PID can be simulated and displayed by Matlab to evaluate the control effect. In the end, the experiment is made to validate the control arithmetic. The compared results show that the fuzzy PID controller is better than conventional PID used in monitoring system for construction machinery.
