研究目的
To study and build a bionic eye platform, and to verify the motion mode of the bionic eye through the common motion control algorithm such as PID control and sliding mode control.
研究成果
The designed bionic eye platform successfully imitates human eye movement with good performance on object tracking. Both PID and sliding mode controllers were effective, with sliding mode control providing smoother trajectory tracking. The platform serves as a valuable experimental setup for validating control methods in bionic eye systems.
研究不足
The platform's control precision and speed are limited by the motor and encoder specifications. Nonlinearities in the system model, such as friction, pose challenges for control algorithms.
