Latest Patents

Mori's latest patents include a "Sampled-data I-PD control apparatus" and a "Multivariable proportional-integral-derivative process control apparatus." The sampled-data I-PD control apparatus is designed to manage an interference multi-input/multi-output process through an I-PD action. This innovative apparatus features an identification signal generator that superposes persistently exciting identification signals on control variables of the process. It also includes an identifying circuit for determining the pulse transfer function of the process based on its control and output variables. Additionally, an S-transfer function calculator transforms the identified pulse transfer function, while a tuning circuit aligns the S-transfer function with that of a process model, adjusting the sampled-data I-PD control parameters accordingly.

The multivariable proportional-integral-derivative process control apparatus identifies the dynamic characteristics of a process based on its inputs and outputs. This allows for the tuning of digital PID parameters in accordance with the identified characteristics. The process is characterized as an N-input/output system, where the interactions between inputs and outputs are taken into account. Each transfer function between a specific input and output is identified, and a transfer function between a set-point signal and the process output is matched with that of a decoupled reference model to optimize the PID parameters.
