“…Although there are many satellites, which have active temperature control themselves and by thermal analysis the constant temperature point for installing the sensor could be found. The temperature error can also be compensated by analytical methods 26 and also, temperature robustness can be investigated in detailed design. 5,27 However, the authors of this paper focused on conceptual design and this issue will definitely be considered in future works.…”

Spacecraft attitude determination is a crucial task in attitude control subsystems. It provides the necessary feedback to close the control loop. Several sensors such as star trackers, Sun sensors, and horizon sensors are used for this purpose. The development of other methods can help control engineer with newer options to design their systems. Here, an innovative sensor for determining the attitude of a spacecraft is presented. The proposed sensor measures the Lorentz force vector due to the interaction between the magnetic field of the Earth, and the high linear velocity of the spacecraft. This sensor is composed of three series of orthogonal variable capacitors. The capacitors are connected in parallel to increase the total capacitance. The capacitors have movable plates which actuated by alternating current with specific frequency. Due to very high speed of spacecraft relative to magnetic field of earth in low orbit, the Lorentz force is exerted on the charges of the capacitor plates. The plates have same velocity as the spacecraft does. The applied Lorentz force to the plates affects their motion so that the harmonic can be seen in the output. Measuring the amplitude of the mentioned harmonic results in measurement of a component of the Lorentz force in the direction of capacitors. Installing the three capacitors orthogonally can measure the three rectangular components of the Lorentz force. This vector will be in the body frame of the spacecraft. The two-plate and three-plate capacitor are the two different proposed mechanisms and their performance is compared. Once the Lorentz force is known as a vector in the body frame, it can be applied along with data from another sensor to determine the attitude of the spacecraft. Based on simulation results, achievable resolution is better than 3°, which can be improved by further research.

“…The proof mass ( 9) is connected to the decoupling frame (2) with the spring suspension (10), the Y-axial rigidity of which is much higher than the X-axial. The proof mass (9) is also connected to the object via the spring suspension (11), the X-axial rigidity of which is much lower than the Y-axial. Thus, the proof mass (9) is not involved in the primary oscillations along the Х-axis.…”

Thus, at disturbing factors, the primary oscillation control system must provide and maintain the value trimming resulting in the simultaneous stabilization in frequency and amplitude of primary oscillations [10,11].…”

The mode of primary oscillations of a micromechanical gyroscope (MMG) sensor is provided by an electrostatic comb-drive actuator in which the interaction between the micromechanical structures and electronics occurs by means of a single or differential capacitive sensor. Two pairs of capacitive sensors are traditionally used for frequency stabilization of MMG primary oscillations. The first pair of capacitive sensors excites primary oscillations, while the second measures the amplitude of primary oscillations. The stabilization system provides a continuous frequency tuning of primary oscillations that increases the duration of transition processes, the time of operational readiness, and the instability of the output signal from the secondary oscillation channel of the MMGs. This paper presents a new approach to the primary oscillation control system of the two-component MMG. The method of calculating the natural resonant frequency is based on measurements of the total current passing through the comb-driver actuator capacitances, and a lock-in detection is suggested. This paper consists of the results of the numerical analysis, the description of the proposed approach to the frequency control of the primary MMG oscillations, and the Simulink model of the behaviour of the MMG stabilization system, depending on its mechanical-and-physical properties with regard to a 2% shift of the natural resonant frequency. The frequency control of the primary oscillations at 2% frequency detuning is performed within 0.11 s.

The fast response temperature sensor is an effective tool for measuring the temperature of internal combustion engine, in order to improve the performance of fast response temperature sensor, and the Coiflet wavelet finite element method is applied in analyzing the heat transfer rules of fast response temperature sensor. Firstly, the related research progress on the performance analysis of fast response and wavelet finite element method is summarized, respectively, and research significance of heat transfer of fast response sensor based on Coiflet wavelet finite element method is summarized in detail. Secondly, the basic theory of fast response sensor is studied, and the new structure of the fast response temperature sensor is analyzed. Thirdly, the Coiflet wavelet finite element model of analyzing heat transfer of fast response sensor is constructed by combing the Coiflet wavelet scale function with traditional finite element method, and the theoretical models are deduced. Finally, the heat transfer simulation of fast response temperature sensor based on Coiflet wavelet finite element method is carried out, and simulation results show that the Coiflet finite element has higher computing precision and efficiency than traditional finite element method, and the heat transfer rules of fast response temperature sensor are also obtained.Keywords Coiflet wavelet finite element Á Heat transfer Á Fast response temperature sensor During the working process of the internal combustion engine, the temperature and pressure of the low-temperature working media can increase through the combustion of mixture refrigerant concluding air and petroleum fuels, and then the working media can do expansion work. In the process of combustion, the temperature of the working medium will suddenly increase, and the process time should be measured in seconds. Because temperature changes rapidly, the general temperature sensor has difficulty measuring the temperature of the working medium accurately, and therefore the fast response temperature sensor should be used. Currently, there are many sensors; however, these sensors have many disadvantages when they are used to measure the temperature of the internal combustion engine; for example, the platinum resistance thermometer has low response speed and big volume, the thermistor is volatile in high temperature, and the radiation thermometer is not suitable for measuring the temperature of closed cavity. Therefore, the new fast speed sensor should be used to measure the temperature of internal combustion engine, which has fast response when it is used to measure temperature of internal combustion engine. However, the temperature change in fast response sensor has strong nonlinearity when it is used to measure temperature of internal combustion engine, and therefore the advanced numerical analysis method should be used to analyze the temperature of fast response sensor. The wavelet finite element method has the characteristic of multi-resolution analysis, and the complex degree of nonlinear analys...
