Soft sensor development based on kernel dynamic time warping and a relevant vector machine for unequal-length batch processes

作者:

Highlights:

• A kernel DTW algorithm combining the kernel trick is designed.

• An adaptive selection strategy for the optimal parameter is proposed.

• A novel soft sensor is proposed for unequal-length batch processes.

• A penicillin fermentation process is used to verify the proposed soft sensor.

• The proposed soft sensor has better performance than other soft sensors.
