APPLIED NEURAL NETWORK BASED PID CONTROLLER (PIDNN) IN DESIGN AND TEST ANTI-VIBRATION SPOON

Abstract

Today, hand tremors are a fairly common movement disorder. There are many
possible causes of hand tremors, but there is currently no specific treatment.
Although it has a great impact on the patient's life, support tools for patients with
hand tremors have not been paid much attention, especially in Vietnam [1]. For
that reason, we has studied the design of the anti-vibration spoon with the aim of
minimizing the vibrations from hand to the spoon during the patient's life. Device
includes an IMU accelerometer (Inertial Measurement Unit) to detect the vibrations,
and at the same time uses the motors to move the spoon face against the direction
of the vibration. The process is controlled by a Neural Network based PID adaptive
controller (PIDNN). Research results show the feasibility of the device and the ability
to complete the replication on the patient.
