(Ws, Pa) obtains the high-precision environment real time temperature Tg crossed through error correction.Then user can be defeated to TFTLCD display screen
Entering default relative humidity Rw, water temperature Tw, Te are that high-low-temperature temperature test box water temperature gathers with cooling-water temperature sensor
The difference of real time temperature Tg.
(2) according to the real-time relative humidity Rg obtained by step (1), set relative humidity Rw, Real-time Water temperature Tg and
The water temperature Tw set, is calculated relative humidity differential valve system error e 1 by microcontroller and temperature gap system is missed
Difference e2.Carry out PID duty ratio modulation according to relative humidity differential valve system e1, temperature gap systematic error e2, and then pass through PID
Humidifier, heater are humidified by control algolithm, computer heating control, so that household humidifier is operated in a most effectively model
In enclosing.
When being embodied as, record uses Levenberg-Marquardt algorithm controls and PID to control；Levenberg-
Marquardt algorithm, simulates formula by algorithm, and it is according to relative humidity differential valve system e1, temperature gap that pid algorithm controls
The deviation of systematic error e2, by deviation in proportion, integration and differential constitute controlled quentity controlled variable by linear combination, controlled variable is carried out
Control.The water temperature of the method that combines, relative error and the time of advent, at a temperature of being recorded simultaneously at same settings, independent PID
The water temperature of control method, relative error and the time of advent.As shown in table 1, wherein, initial water temperature is 47.2 DEG C.
Analyzing the data obtained, the method using Levenberg-Marquardt algorithm controls and PID to control to combine can
Temperature error is controlled at about 0.1 DEG C, and relative error is less than 0.5%.This device is single compared to tradition in terms of temperature control
PID controls, and has response time fast, and relative error is little, degree of accuracy high.
