How can you document the design and operation of a PID controller for future reference?

There are 4 layers to the triage (hw, fw, sw - hardware, firmware, software) data footprint. [Layer 1] Measured Power Driver (Electrical, Magnetic, Optics, Gravimetric, Pneumatic, Hydraulic, Frequency, etc) "something" that shifts "the Variable" being Moved; [Layer 2] MeasurING InPut devices (Level, Position, Flow, Pressure, etc.); [Layer 3] Live InPUT Data Value(s) Massage (Scaling, Range, Repeatability, Boundary Accept-Reject Limits, Multivariate algorithms, etc), [Layer 4] Live OutPUT Data Value AND SYSTEM Power Driver response RATE (IF Rate = 5x to 8x of Need THEN "is Good"; IF Rate = 8x to 10x of Need THEN "is Great"). Use PID for Set Ranges of "Good(or Better)" Multivariate RATE only. Turn PID OFF otherwise.

First and foremost ensure that the measuring instruments are placed to provide the best possible dynamics, especially deadtime, for the controller. You do not want to see lag and/or deadtime being dominated by the feedback instruments. Secondly, you should identify early in the design whether the adoption of techniques such as cascade, feedforward or adaptive tuning will be useful. Lastly, understand the likely process dynamics before you start. A fast self-regulating process is usually more forgiving than a big fat slow integrating process. This will not only impact on your final tuning but should make a difference in the selection of the final design of your loop

To set up a PID loop: Define desired control goals, specify input/output signals, choose appropriate sensor and actuator, and select PID parameters. Document the process clearly for future reference. Design the loop considering system dynamics and control objectives. Finally, ensure smooth operation by testing, tuning, and monitoring performance.

The PID controller output is calculated by simply adding the Proportional, the Integral and the Derivative. Depending on the gain setting of these three values, will determine how much effect they will have on the output.

There is a Primary and a Secondary concern: Primary is "the Range of Operation" of the PID, Secondary is "the Tuning Parameter Set of Data" used in EACH of the Ranges of Operations. As an example: (f,g,h,j,k) are Range Variables and (PID of "q") is the Operational Gain Controller (p,i,d)q for (f,g,h)=(-12, 34, 6)Lo to (84, -12, 180)Hi (p,i,d)q = (p(n), i(n), d(n)) where n = 12th in a Set of changing Setpoints. As the Rate of Machines and Processes change so do the Response Rate(s) per Unit time of controllers change with Gain, Integral Time, Derivative Time altered to tighten(loosen) controller times

Document the PID controller's design and operation by detailing its parameters, tuning methods, and performance criteria. Include diagrams or schematics illustrating the control loop, as well as any software or hardware configurations. Document test results, tuning adjustments, and any observed behaviors for future reference and troubleshooting.

A PID controller, including its design parameters, mathematical equations, control algorithm, tuning procedure, operating instructions, performance evaluation, troubleshooting steps, and maintenance tasks. It also includes references to relevant literature, manuals, and resources used during the design and implementation of the controller. The summary emphasizes the importance of understanding the PID controller's purpose, performance evaluation results, and routine maintenance tasks to ensure optimal performance.

Es importante definir el metodo de operacion , particularmente para aplicaciones de SVC o de Filtros activos de potencia trabajamos realizando primero el análisis de estabilidad y el dise?o del control a partir de las variables de estado del sistema a implementar , particularmente los modelamientos que he realizado han sido en Simulink y la librería SymPowerSystem , lo mas trabajosos es hallar los valores k que hacen estable el sistema

An extremely important part of designing any PID controller is to properly document the different test scenarios and combinations used in the PID and their results based on the defined application (do we need a fast response with little error? a slower response etc..) . Its important to clearly label what variable was changed during this run and how did the output change with respect to the input (as per desired output outcome), the best way would be a tabular format, listing all the different constant values (proportional kp, integral ki and derivative kd) used and outputs that match them to draw a conclusion on the combination that provides the best response type based on application with the least error possible.

To document the design of a PID controller for future reference, record the controller's parameters such as proportional, integral, and derivative gains, along with the process model and tuning method used. Include any simulations or experimental data demonstrating the controller's performance under various conditions. Additionally, document any modifications or adjustments made during the tuning process and their rationale. This comprehensive record ensures replicability and troubleshooting for future reference.

Documentar o projeto e a opera??o de um controlador PID é crucial para referência futura e para garantir a consistência e eficácia do sistema. Descreva o processo de sintonia do controlador. Isso pode incluir métodos como o método de Ziegler-Nichols ou outros métodos específicos. Registre os valores dos parametros PID (kp, Ti, Td) após a sintonia.

It is important to choose the right design method according to the application. It is also important not to cause irreversible damage when debugging the system (boiler explosion, solidification of molten glass in the tank when adjusting the regulator, etc. It is also important to properly design the electrical part so that it is safe, reliable during operation, resistant to external environmental influences, but also to hackers.

Writing report can be a challenging tasks but there is always a guide on how to properly do it. Master on how to deliver the information, adds up something that will make sense and will not ruin and cause confusion. Attachments are very helpful to someone reading on it to make them visualize on what do you want to say.

PID loops are always a tricky matter to get right, they require periodic fine-tuning and review based on their inputs also, so keep in mind that your control system is as good as your data and sensors, if your sensors are reading bad data then this will throw off your PID loop no matter how fine-tuned it is, so always make sure your on-site equipment are maintained to the level that the design was built so your minimize your time fine-tuning the PID later on .
