PTD Controller is widely used as autamatic equipment for industry. However, when a system has various characters, parameter· decision and tuning for accurate control is a hard task. In this paper, expert auto-tuning PID controller using PLC is presented as alway of solving this problem. Expert auto tuning algorithm is based on Ziegler-Nichols step response and expert knowledge. The test of control performance is carried out in practical speed control of Induction Motor in variable load, the experimental results suggest its superior performance.
