“…The determination of the angular acceleration values on the rotary axes is calculated. This option is preferred because the gyroscopic sensor that is inserted into the MPU-6500 sensor has the disadvantage of obtaining a so-called 'drift' upon measurement (Li et al, 2019). The determination of the angular acceleration values is made by the following mathematical relations:…”

In the present work, a system using data from two sensors located next to the driver and to the mass centre of the bus is proposed. Three degrees of discomfort have been used – comfortable, moderately uncomfortable and very uncomfortable. These levels are set out in the questionnaire. A survey was conducted. Respondents were selected between the ages of 14 and 65 and were divided into three age groups – adults, middle-aged and young. Accelerometer systems with MPU-6500 (TDK InvenSense Corp.) sensors are used. A correlation method (CORR) and sequentially improving estimation methods are used for feature selection, which significantly reduce the number of combinations of features obtained. Selected sensor data is entered into feature vectors. These vectors are reduced by principal component analysis. Predictive models have been created that take into account the age of passengers. The use of data from two sensors and separation of the passengers according their age, leads to an increase in the accuracy of predicting passengers discomfort level (DL) of up to 98%. These results can be used to evaluate and guide the vehicle driver in order to improve his driving style. In addition, the simplified interface does not distract the driver from the road conditions. The results obtained can lead to an improvement in the parameters of the transport process, which covers the interest of the carrier related to the efficient use of vehicles, and hence the reduction of fuel consumption and harmful emissions. However, it should be recommended that, when developing systems to ensure comfort of travel, adjustments should be made to suit the age group of passengers carried on public transport buses.

“…The models proposed in this paper, depending on the age of the respondents, increase this accuracy to 98%. The results presented by Ikeda et al [8], where the authors evaluate the degree of discomfort in one respondent, mainly take into account the vertical vibration only. Kim et al (2014) proposed a system using neural networks.…”

“…Existing methods for compensating this gyro drift tried to correct the sensor measurement. These methods either calibrate the gyroscope [19], filter measurement error [16], or correct the orientation measurement with additional sensors [18]. However, they often struggle to preserve their effectiveness, especially in harsh operating conditions.…”

This paper presents a robust fault-tolerant control scheme that provides reliable tracking and effective disturbance rejection for a low-cost tracking system. As the controlled apparatus, a 2-axis gimbaled mechanism is involved in a networked control system, and an unreliable sensor brings sensor drift into the system. Besides, external disturbances heavily affect the system in practical applications. Representation of the faulty gimbal system with its constraints and disturbances is firstly introduced. Then, the designed fault-tolerant controller consists of two components: (1) an unknown input observer estimates simultaneously information on the fault and effect of disturbances and networked delay, and (2) a robust control law, using the observer estimations, is based on the combination of the super-twisting algorithm, backstepping procedure, and integral sliding mode control technique. Subsequently, simulations and experiments are conducted, in which the performance of the proposed control system is compared to those from the previous studies. The results show the superiority and reliability of the proposed control system.INDEX TERMS Fault tolerant control, target tracking system, time-varying delay, unknown input observer, sensor drift, integral sliding mode control.

“…There are many kinds of transducers in present micromechanical accelerometers, such as capacitive, piezo-resistive, electromagnetic, optical, thermal convective, acoustic waves resonant, field emission, tunnel transducers and so on [6]. The micromechanical accelerometers with capacitive transducers are widely used due to relatively simple transducer structure, high-sensitivity, reliability, thermal stability, excellent linearity, resolution, bandwidth, good compatibility with integrated circuits technology, and consequently low cost [7][8][9][10][11][12][13][14].…”

“…Moreover, the switching-capacitor charge-based technique is conventionally used in closed-loop SPD to effectively suppress flicker noise [19]. Therefore, voltage control closed-loop SPD are frequently used today especially for high-sensitivity and high accuracy MEMS accelerometers [8][9][10][11][12][13]. However, there are the following disadvantages of voltage control closed-loop signal processing devices:…”

Highly Sensitive Signal Processing Devices for Capacitive Transducers of Micromechanical Accelerometers

et al. 2019

View full text Add to dashboard Cite

In this paper, the principles of the open-loop frequency-based signal processing devices for capacitive MEMS accelerometers are used to develop three CMOS IP-core (Intellectual Property core) projects of highly sensitive signal processing devices with frequency output. Signal processing devices designed in accordance with the considered method form an output of rectangular pulses whose frequencies equal a difference of signal frequencies from two identical generators with micromechanical accelerometer capacitive transducers in their frequency control circuits. First, the analog project scheme uses two harmonic LC oscillators and an analog mixer to form an output rectangular-shape differential-frequency signal, the frequency of which is dependent on the measured acceleration. Second, the digital project is fully scalable for various CMOS-technologies due to oscillators of rectangular pulses and a digital mixer. Third, the mixed-signal project combines the advantages of the analog and digital projects. The signal processing device projects were developed, modeled and compared to comprehensively solve the problems of increasing sensitivity, dynamic range, noise immunity and resistance to destabilizing factors (e.g., to temperature changes).
