“…Thus far, PID control is still the basic control method in the process industries. PID control technology and its optimized control technology are accounted for more than 90% in accordance with the survey data [20,21]. The PID control algorithm mainly includes the proportional (P), integral (I), and derivative (D) three modes.…”

A modal analysis (MA) was preconsidered to determine a novel active vibration control (AVC) structure of multistage gear transmission system (MGTS) and an appropriate actuating position for the piezoelectric actuator (PZT); the results of the calculating method and the finite element method (FEM) were compared to validate the reliability of MA. The controllers based on different control algorithms were designed to drive the PZTs to output the control force for suppressing the host structure vibrations. To analyze the feasibility of the applied control schemes and discuss the control effects dominated by the different control algorithms, a series of active vibration control numerical simulations were studied. The cosimulation results validate the practicability of the proposed control schemes and provide a forcible guidance for the further experimental works.

“…13) Theoretical and experimental studies using a novel PTC material at a room temperature Curie point achieved the highest precision of approximately 0.01 C. 14) Furthermore, a new thermal control method in which PTC material is combined with a PID control algorithm was proposed to effectively reduce overshoot and increase temperature control precision. 15) The thermal design methods described above can achieve high-precision temperature control. However, these design methods increase the complexity, weight and cost of the thermal control system; especially if more precise temperature control is required.…”

High-precision, temperature control technology is currently an important research field in spacecraft thermal control. High-precision temperature control based on grading-structure and PID-feedback strategies determine by theoretical analysis and grading a thermal control experiment is proposed in this paper. A sensitivity analysis of the key parameters influencing temperature control precision is investigated. The key parameters mainly include the inner emissivity of the transition section ¾ t , outer emissivity of the central section ¾ c , effective emissivity from the transition section to the central section ¾ i/o , inner emissivity of the central section ¾ i , outer emissivity of the equipment ¾ eq , outer emissivity of the mounting plate ¾ d , electronic equipment power P e , and the conductivity coefficient of the equipment mounting insulation pad . Both the theoretical and experimental results show that the strategies developed during this research can achieve temperature control precision better than 0.05 o C (or «0.025 o C). Parameters ¾ t , ¾ eq , and ¾ d not only influence the temperature level, but also influence steady time. P e , ¾ c , and ¾ i only influence the temperature level. ¾ i/o not only influences the temperature level, but also influences temperature control precision. Thermal conductivity influences temperature level rather than temperature control precision because of the active temperature control of the mounting plate. This study provides a new method for the high-precision thermal control of equipment in spacecraft and specifies new directions for future research work.

Abstract-The purpose of this study is to achieve large-scale real-time acquisition and monitoring of the patient's body temperature, for noticing abnormal phenomenon of temperature in time. In the ward, arrange ZigBee wireless temperature monitoring network, realize the ward patients temperature measurement and gathering of temperature related clinical data, achieve the temperature monitoring network through the serial RS232 and PC communication, and PC receives, displays, and processes the data through the serial port. The results showed that the system can also realize the acquisition, transmission and monitoring of a plurality of temperature signals, and send out the alarm in abnormal temperature. As a result, the system can be widely used in clinical measurement, suitable for popularization in large hospital with a large number of patients.
