“…To estimate the state of the IMU system, Kalman filters use mean square error minimisation, although they are unable to reduce vibration sounds caused by sensors. As a result, mechanical and certain software-based vibration filters have been designed to address this issue [ 34 ]. Complementary filters can be used with IMU sensors if there are two separate measurement sources for predicting the output variable and their values depend on the frequencies.…”

Wearable sensor technology has gradually extended its usability into a wide range of well-known applications. Wearable sensors can typically assess and quantify the wearer’s physiology and are commonly employed for human activity detection and quantified self-assessment. Wearable sensors are increasingly utilised to monitor patient health, rapidly assist with disease diagnosis, and help predict and often improve patient outcomes. Clinicians use various self-report questionnaires and well-known tests to report patient symptoms and assess their functional ability. These assessments are time consuming and costly and depend on subjective patient recall. Moreover, measurements may not accurately demonstrate the patient’s functional ability whilst at home. Wearable sensors can be used to detect and quantify specific movements in different applications. The volume of data collected by wearable sensors during long-term assessment of ambulatory movement can become immense in tuple size. This paper discusses current techniques used to track and record various human body movements, as well as techniques used to measure activity and sleep from long-term data collected by wearable technology devices.

“…Measurement unit of accelerometer typically in gravitational motion (g) where 1g is equivalent to 9.8m/s2 which is acceleration cause of earth gravity. However, for linear displacement measurement, recorded data need to be integrated two times which tend to drift over a time and very sensitive to environmental noise [5], [18]. In other way, from an accelerometer, a tilt angle can be sensed and estimated as described on Freescale Semiconductor Application Note used by [37].…”

“…Nowadays, advanced in technology innovates to combine mechanical and electrical components into micro-scale object calls as Microelectromechanical systems (MEMS) [1], [2]. With MEMS technology component being inexpensive, small size, low power consumption, therefore products are redesigned to include such as an inertial measurement unit (IMU) sensor onto telecommunication, automotive industries and medical application [3][4][5][6]. In robotics, MEMS technology are the main of attitude and heading reference system (AHRS) to determine rotation, motion, location and direction (generally called attitude estimation) of mobile robots for automated navigation, autonomous underwater vehicle (AUV) for global localization systems and unmanned aerial vehicle (UAV) in aviation [1], [6][7][8][9].…”

This paper proposes a sensor fusion algorithm by complementary filter technique for attitude estimation of quadrotor UAV using low-cost MEMS IMU. Angular rate from gyroscope tend to drift over a time while accelerometer data is commonly effected with environmental noise. Therefore, high frequency gyroscope signal and low frequency accelerometer signal is fused using complementary filter algorithm. The complementary filter scaling factor K1=0.98 and K2=0.02 are used to merge both gyro and accelerometer. The results show that the smooth roll, pitch and yaw attitude angle can be obtained from the low cost IMU by using proposed sensor fusion algorithm.

This paper presents sensor fusion algorithm using nonlinear complementary filter (NCF) for attitude estimation and a proportional-integral-derivative (PID) controller for small-scale quadrotor unmanned aerial vehicle (UAV) stabilization. From inertial measurement unit (IMU) data, gyroscope as a main sensor is fused to another two sensors; accelerometer and magnetometer to correct drift error of gyroscope to obtain reliable attitude estimation. In this paper, the performance of NCF is implemented on real-time while applying PID controller for attitude stabilization of quadrotor UAV during hovering. Experimental results show the effectiveness of PID controller for quadrotor UAV stabilization during attitude control  .
