Experimental Investigation on Fuzzy PID Control of Dual Axis Turntable Servo System

摘要

The paper presents a fuzzy PID control method for a dual axis turntable servo system, which is used to reflect the sun light to the window of the residents. First, the mathematical model of dual axis turntable is established, which is expressed in the state space. Second, a fuzzy PID control method is proposed, and the parameters of PID controller are adjusted online by fuzzy logic to be optimized. Third, the simulation module is built in Matlab to prove the effectiveness of the fuzzy PID method, and it shows that the fuzzy PID method can meet the task requirement. At last, the experiments are performed to verify the rationality and feasibility of the dual axis turntable servo system.
