Abstract: Soft sensors offer an alternative approach for measuring process variables that cannot be directly obtained from hardware sensors, crucial for optimizing process outputs. This paper outlines a method for implementing an embedded soft sensor to estimate lactose concentration in a bioreactor using the MicroBlaze Soft Processor found in the Zynq SoC. The study focuses on employing the Extended Kalman Filter (EKF) algorithm for this purpose. The methodology involves designing a block using the MicroBlaze soft processor core in VIVADO, utilizing the Zybo board as the hardware platform. The embedded soft sensor is developed as a software application in C, configured to operate on the soft processor within the Zynq device. A comparative analysis is conducted among lactose output values obtained from simulation, hardware implementation, and true values derived from laboratory analysis. This approach underscores the efficacy of embedded soft sensors in enhancing process monitoring and optimization.
