Abstract: A fuzzy inference processing apparatus based on fuzzy rules represented by an if-then notation comprises a CPU having a software for obtaining grades of if-part membership functions with respect to input variables for each rule and a hardware for obtaining a truth value of the if-part of each rule, a truth value of the then-part of each rule, and an inference result. The hardware comprises a predetermined number of then-part membership function calculators for respectively storing the then-part membership functions defined in the then-part of the rules, minimum calculators respectively connected to the then-part membership function calculators, and a maximum calculation circuit connected to all the then-part membership function calculators. The CPU supplies the grades of the if-part membership functions for each rule to one of the minimum calculators which is connected to the then-part membership function calculator storing the then-part membership function defined in the then-part of the rule.

Abstract: In a process control system prior to execution of process control, a manipulated variable to which an identification signal from an identification signal generator is added is inputted to a process. In a preadaptation section, a controlled variable output from the process is sampled to obtain its dead time and maxmum gradient, and the initial values of PID control parameters are calculated on the basis of the dead time and the maximum gradient. The initial values of PID control parameters and the like are set in the adaptation section. In the adaptation section, a pulse transfer function of the process is acquired, and PID control parameters are calculated from the acquired pulse transfer function by using a partial matching method in a frequency region. After these PID control parameters are set in a control section, process control is executed.

Abstract: A determination and control section of a process control system samples a set value, a difference value, a manipulated variable, and a controlled variable to determine a state of a process. When it is determined that the process is in an unstable state, an adaptive unit estimates a dynamic characteristic of the process, and calculate PID control parameters using a partial model matching method in a frequency region. When it is determined that the process is in an insufficient response state, the PID control parameter is regulated without operating the adaptive unit to decrease the gain of the process control system.
