Title: Pid control method
Inventor: SEKOZAWA TERUJI
IPC: G05B13/02
Filed: 1983-01-28
Abstract: PURPOSE:To reduce the cost and to operate a process adaptively to even disturbance flexibly by calculating a forgetting factor, which is a parameter determining availability, on a basis of an identification error in an identifying part which identifies the process. CONSTITUTION:In a PID controller 6 of the process which controls automatically the temperature and etc. in a plant, a deviation e(t) between a control target r(t) and a control signal y(t) outputted from a process 1 is operated in an operating part 5. An operation signal u(t) of the process 1 is generated from a manipulated variable operating part 2 on a basis of this deviation, and PID parameters are adjusted in an identifying part 3 and a control parameter operating part 4. Though the identifying part 3 uses a preliminarily given forgetting factor to operate the identification quantity of the process, this forgetting factor is adjusted at every synchronous gamma by sampling control, and an information quantity attained by weighing the quantity, which indicates an identification error at a time (t+gamma), with parameters including the forgetting factor at a time (t) is used for this adjustment.

Title: Plant cell culturing
Inventor: SATO KENJI
IPC: C12N5/04
Filed: 1996-01-26
Abstract: PROBLEM TO BE SOLVED: To continuously culture plant cells in a stationary state under an increased production of secondary metabolic products by determining a phosphoric acid concentration that gives a desired specific growth rate and cell concentration using a relational expression between a growth rate of plant cells and a phosphoric acid concentration in a medium and using a medium having the determined phosphoric acid concentration. SOLUTION: In a method for culturing plant cells in a liquid medium, a phosphoric acid concentration that gives a desired specific growth rate and cell concentration is determined using the equation (X is a cell concentration; S is a phosphoric acid concentration; μm is the maximum specific growth rate; KM is a saturation constant) obtained from the relation between a growth rate of the plant cells and the phosphoric acid concentration in a medium. Plant cells are cultured using a medium having the determined phosphoric acid concentration. In the culturing, the phosphoric acid works as a restricted substrate, and thus, while breading plant cells for producing seedlings, plant bodies such as seedlings and bulbs can be produced in a large scale.  The processes enable the continuous culturing of plant cells in a stationary state under the production cost reduction and the stable supply of seedlings, and the improvement of the production efficiency of secondary metabolic products such as anthocyanin.
