By using the dynamic compensation method, the correct compensation of the output of the gas sensor can be ensured when the temperature changes or the response / recovery process switches.

[0075] In the present disclosure, the gas concentration in the response process changes from low to high, and the gas concentration in the recovery process changes from high to low. The response duration and the recovery duration refer to different characteristic durations of the two processes, and the specific standard is the time used to reach the change N% of the ambient gas concentration, where N is, for example, 63, 78, etc., and the present disclosure does not limit the same.

[0076] Further, a low-pass filter can be added in the compensation process to reduce the amplification of high-frequency noise.

[0077] Please refer to Figure 2 , Figure 2 A flowchart of a dynamic compensation method of a gas sensor according to another embodiment of the present disclosure is provided, which comprises offline identification of a to-be-compensated gas sensor system in a constant temperature experimental environment, and the lower part is online dynamic compensation of the to-be-compensated gas sensor in actual application.

[0078] The offline identification of the to-be-compensated gas sensor system in the constant temperature experimental environment comprises the following steps 1) and 2):

[0079] 1) Step test of the to-be-compensated gas sensor in the response process and the recovery process in the constant temperature experimental environment.

[0080] 2) According to the actual gas concentration N in，ex in the constant temperature experimental environment and the measured gas concentration N out，ex of the to-be-compensated sensor, the corresponding response process compensation filter ∑ res and the recovery process compensation filter ∑ rec are identified by least square method or particle swarm, neural network, etc.

[0081] Online dynamic compensation of the gas sensor to be compensated includes the following steps 3)-6):

[0082] 3) Select the shorter of the response time and the reply time, and choose the corresponding compensation filter as the isothermal compensation filter ∑. c0 This is to ensure that the compensation results converge.

[0083] 4) Through the compensation filter ∑ c0 The compensation filter is determined based on the measured current ambient temperature T(k) to vary with temperature.

[0084] 5) Based on the gas concentration measurement result N of the sensor to be compensated at the current ambient temperature. out (k) and temperature-varying compensation filter The gas concentration measurement result N after compensation was obtained. inC (k), where a low-pass filter can be added during the compensation process to reduce the amplification of high-frequency noise by the compensation.

[0085] 6) Based on the compensated gas concentration measurement results N inC (k) and the gas concentration measurement result N measured at the current ambient temperature. out (k) Determine the state of the sensor (compensation result N) inC (k)>N out (k) represents the response process; the compensation result N inC (k)<N out (k) is the response process; check if this state matches the one selected in (3). If they match, output the compensation result N. inC (k); if inconsistent, return to 3) select another compensation filter.

[0086] In this disclosure, the transfer function of the compensation filter selected in step 3) is assumed to be:

[0087]

[0088] The temperature result T(k) is used to convert it into a temperature-varying compensation filter. ∑ c0 Convert to state-space form:

[0089]

[0090] If the temperature is assumed to be constant within a measurement cycle, it can be transformed into a state transition matrix form:

[0091]

[0092] in, The relationship between response time (or recovery time) and temperature can be expressed as: t0 / t * = f (T / T0), where t0, t* are the response (recovery) times at temperatures T0, T respectively.

[0093] Ignoring the case of temperature change within a measurement period, it can be considered that high / low temperature accelerates / decelerates the response (recovery) process, and for a single measurement period, it can be equivalent to lengthening / shortening the measurement period under the condition of constant temperature. Therefore, the state transition matrix of the temperature-varying compensation filter can be expressed as Then Thus, the state space equation of the temperature-varying compensation filter is:

[0094]

[0095] Thus, the compensation filter can be obtained. Through the compensation process in Figure 2 , the dynamic compensation gas concentration output N inC (k) can be obtained.
