“…The basic principle of operation of a MEMS accelerometer is to measure the proof-mass displacement caused by the applied acceleration. Several technologies can be used to measure this displacement, such as capacitive technology [5][6][7], piezoelectric-based approaches [8], piezoresistive-sensing methods [9], and magnetic and optical techniques [10,11]. Each sensing technology not only provides several advantages but also suffers from some drawbacks.…”

This paper proposes a novel graphene‐based optical microelectromechanical systems MEMS accelerometer that is dependent on the intensity modulation and optical properties of graphene. The designed sensing system includes a multilayer graphene finger, a laser diode (LD) light source, a photodiode, and integrated optical waveguides. The proposed accelerometer provides several advantages, such as negligible cross‐axis sensitivity, appropriate linearity behavior in the operation range, a relatively broad measurement range, and a significantly wider bandwidth when compared with other important contributions in the literature. Furthermore, the functional characteristics of the proposed device are designed analytically, and are then confirmed using numerical methods. Based on the simulation results, the functional characteristics are as follows: a mechanical sensitivity of 1,019 nm/g, an optical sensitivity of 145.7 %/g, a resonance frequency of 15,553 Hz, a bandwidth of 7 kHz, and a measurement range of ±10 g. Owing to the obtained functional characteristics, the proposed device is suitable for several applications in which high sensitivity and wide bandwidth are required simultaneously.

“…In order to compensate these effects, different methods exist. While noise, mismatch-and offset-errors can be suppressed by complex circuit topologies, different design techniques or additional components [1,2], influences from process variation, varying temperature or varying supply voltage (PVT influences) can be conquered by a complementary circuit design or special layout techniques [3,4]. Nevertheless, all of these methods significantly increase the design time and costs of the interface.…”

On-Line Error Correction in Sensor Interface Circuits by Using Adaptive Filtering and Digital Calibration

Numerous non-ideal effects can distort the functionality of sensor interfaces and have to be considered during the design phase. In order to relax the requirements for the analog circuit components, adaptive filtering and digital calibration are used in this work to detect and correct different gain-and offset-errors. The error detection is performed by transmitting a test signal through the sensor interface continuously and in parallel to the sensor signal. In the digital domain, variations of the test signal are evaluated and present errors can be determined and eliminated. In this way, an on-line error correction is realized, which makes the sensor interface more robust against static and dynamic non-idealities. The proposed concept is demonstrated by correcting different gain-and offset-errors in a 65nm CMOS sensor interface.

“…However, some random time-varying delays of environment interference and network may cause the 4WIDEV system to be unstable. On one hand, since the working environment of 4WIDEV changes tremendously, some interferences increase in the conditions of road [4], the variational parameters of motors, the variational parameters of 4WIDEV [5][6][7], and electromagnetic interference (EMI) [8], which are random and difficult to measure. On the other hand, 4WIDEV controls are also characterized by fast dynamics, whereas the response time and accuracy of controller may be influenced under the network-induced delays.…”

The random time-varying delays would reduce control performance and even deteriorate the EV system. To deal with random time-varying delays and achieve a real-time steady-state response, considering randomness of delay and a rapid response, anH∞-based delay-tolerant linear quadratic regulator (LQR) control method based on Taylor series expansion is proposed in this paper. The results of cosimulations with Simulink and CarSim demonstrate the effectiveness of the proposed controller through the control performance of yaw rate, sideslip angle, and the running track. Moreover, the results of comparison with the other controller illustrate the strength of explicitly.
