To easily decide parameters of a model structure of a controlled object suitable for non-interference control. Parameters K and T of a model structure (A structure) comprising a plurality of inputs and a plurality of outputs, wherein a difference on the output side is fed back to the input side, are calculated based on parameters a and b of a black box model (P structure) calculated through system identification or the like in accordance with predetermined conversion expressions K=f(a,b) and T=f(a,b).

A customer submits a service application by accessing the home page of a service provider through a personal computer, and transmits the data including the operation amount and the control amount of a temperature controllerto a serverof the service provider. The serveraccumulates the received data, and in accordance with the contents of the received service application, processes the accumulated data and provides the services of calculating the control parameter for the temperature controller, producing a model of the object of control and making a diagnosis by checking for a temperature control fault.

A temperature variation of a glass substrateat a plurality of measuring points in a continuous furnacewhen preset temperatures of respective furnaces-are changed is estimated in the form of a matrix based on a model, an inverse matrix of the matrix is used so as to calculate correction values in such manner that a temperature of the glass substratecorresponds to a temperature of a desired temperature profile, and the preset temperatures are corrected based on the correction values.

Method, apparatus, and program for controlling temperature within a heating system

When a work is set on a hot plate and a heat treatment is started and the like, an addition waveform of a target temperature is formed based on a previously formed data of an adjustment value, and a temperature is controlled by adding the addition waveform to the target temperature SP, and with the data of the adjustment value, the variation in temperature of the work is prevented using an interference matrix showing a relation between the target temperature SP and the temperature of the work.

In a method of controlling the temperature of a target object by measuring to obtain detected temperatures at a plurality of measurement positions and controlling a processing device such as a heater such that each detected temperature will match the corresponding one of target temperatures set for the processing device, a preliminary step is taken to determine the degrees of interference at the measurement positions by varying the target temperatures and the degrees of interference thus determined are used to correct the set target temperatures or the detected temperatures.

Temperature control method and apparatus

A target value processing unit, includes: an input section to which a target value signal showing a target value of a control process is inputted; a target value shaping unit shaping the target value signal inputted to the input section, into a signal form which is proper for a control treatment of a regulator implementing the control process; and an output section outputting to the regulator a shaped target value signal which is shaped by the target value shaping unit. The target value processing unit realizes the high-level control process without improving the regulator.

A plurality of individually corresponding heaters and temperature sensors are provided along with a plurality of a PID control means. An average temperature/gradient temperature calculating means calculates the average temperatures of the temperatures measured by the temperature sensors and the gradient temperatures based on the measured temperatures. Each of the PID control means outputs an operation signal so that the average temperatures or gradient temperatures may be made equal to the desired values. A distributing means distributes the operation signal from each of the PID control means to each heater so that control by the PID control means may produce no effect on the control of the other PID control means.

Controller, temperature regulator and heat treatment apparatus

A controller controls a physical variable such as temperature of a controlled system. A variable calculator calculates and output a manipulated variable on the controlled system based on of a target value such as a target temperature and a feedback value such as the measured temperature of the controlled system. A dead-time compensator provides a dead-time compensated output using a model simulating the controlled system having a dead time and an idealized model having no dead time, based on the manipulated variable outputted from the variable calculator to carry out an ordinary control and a dead-time compensated control. A switch functions to select the dead-time compensated control by providing a dead-time compensated output to the variable calculator or an ordinary control providing no dead-time compensated output to the variable calculator. The dead-time compensated control is carried out at least during set point response of the controller.

A device to prevent reverse current flow includes a diode connected between a power supply and a load. A switching device, connected in parallel with the diode, has a power loss that is smaller than that of the diode. A low-loss current detector, arranged to turn the switching device on and off, includes a DC current detector and a comparator. The comparator compares the detected DC current value with a threshold value for an operating current and generates an output signal that determines when the switching device should be turned on or off.
