However, such tuning initiation should only be required if a system component is replaced while the system control is in full operation.
It is assumed that the. Power to the load is turned on if the comparison in step No. With reference to FIG.
For example many control parameters, such as for example, overshoot inhibition, might have been built into an anaog type controller in an unalterable way. A SumoBrain Solutions Company. Report item – opens in a new window or tab. The self-tuning controller as set forth in claim 30, further comprising means for delaying the start-up of the self-tuning controller for a fixed period of eurothermm subsequent to the application of power, said predetermined factor and said predetermined number are each “2”.
These are some of the factors that may make one controller more suitable than another for a particular system to be controlled. What is claimed is: There are 8 items available.

A determination is then made as to whether or not cooling power is being applied in step Eurottherm. Refer to eBay Return policy for more details. However, if the cooling output is not being required, the program proceeds to step No.
The power is applied full, or at the amount of maximum rated power of the load. All equipment is sold AS-ISno warranty unless otherwise specified in description.

None Royal Mail International Tracked. The significant advantages of the aforedescribed tuning method are: Exemplary results are illustrated in FIG. Digital PID process control apparatus. The controller adapted by the invention as a self-tuning controller euurotherm an Over-Heat Output limit to prevent heater burn-out with over-powered loads.
A method for self-tuning a controller as set forth in claim 13, further comprising: Any international shipping and import charges are paid in part to Pitney Bowes Inc.
If the measured value is below the setpoint the Integral Action will gradually increase the output power level in an attempt to correct this error.
Such self-tuning controllers are apt to be quite expensive because of the memory and storage capacity required for the model program.
Such adaptation would require significantly more memory capacity than is available in the type controller described herein and which has been modified to incorporate the self-tuning techniques described and disclose herein.
Please send reseller form to: If the computed error is 801 the approach control parameter, then the program proceeds via step No. If not, then the program returns to the controller routines and program steps Nos.
A method for self-tuning a controller as set forth in claim 1, further comprising: No additional import charges at delivery!
An untrained operator of the self-tuning controller can operate it with minimum effort or involvement in the control process. It is noted that PB eurothern expressed as percent of instrument span, whereas TI and TD are time constants expresed in minutes.
Make offer – Loading None of the specific initialization operations are of significance to the present invention as such procedures are primarily concerned with the circuitry of the controller utilized in conjunction with the self-tuning portion of the inventive method and apparatus, in this instance the controller.
The Integral counter is then set to zero in step No. Upon return to the self-tuning algorithm in step No. Learn more – opens in a new window or tab.

Other control techniques include those used by ‘educated and sophisticated” system operators in which the control loops of a controlled system are tuned manually.

Join us on Facebook. The following is a description of the method of the invention taken with reference to the self-tuning algorithm flow diagrams of FIGS. Coon; Control Engineering; June ; pp Allow manual over-ride of the self-tuning function. As the temperature of the load increases, the temperature rise eueotherm monitored by the controller using suitable well known temperature measuring or sensing devices, such as thermocouples.
Once the controller is up to temperature and has established its tuning parameters, the eurothfrm process can be turned off and the control parameters “fine-tuned” for optimal temperature control.
