“…The period of the oscillations, Pcr, and the critical proportional gain are used to find the proportional scalar gain Kp, the integral time Ti and the derivative time Td, with the equations in Table 3 for each PID case. Later, derivative, integral and proportional gain matrixes, Kd, Ki and Kp are found with (10), (11) and (12), respectively.…”

Los sistemas solares de paneles orientables mejoran grandemente su desempeño, basado no solamente en el movimiento en el momento indicado, sino también una adecuada estrategia de movimiento para describir esa rotación. El control de un Sistema de Panel Solar Orientable de dos grados de libertad fue simulado para un esquema de control que combina acciones Proporcional, Integral y Derivativa con un lazo interno de control de par computado. Este lazo interno de control permite el cálculo de torques en las juntas. Fueron evaluadas dos plantas del modelo dinámico del Panel Solar Orientable: analítica y Simmechanics. Tres casos de movimiento fueron simulados: aleatorio, a una posición segura y final del ciclo diario. Las ganancias del controlador se hallaron usando la oscilación sostenida del segundo método de sincronización Nichols-Ziegler. Para ahorrar energía durante el movimiento, se requiere movimiento no subamortiguado, obtenido mediante la anulación de la componente integral del controlador. Errores de posición teóricos muy pequeños para ángulos de elevación y azimut, sugieren que el esquema Proporcional Dreivativo con Control de Torque Calculado es satisfactorio para controlar el movimiento del panel durante el día.

Simplified Controller Design for Output Performance Under Common Input Limitations With Generalized Integral Anti-Windup for a Class of Processes

One of basic key tasks of a control system design is to achieve the desired output responses both in transient and steady states. Besides, the common input limitations, such as saturation and slew rate or at least avoiding a sudden jump in the command signal, must be considered in practice. However, popular controllers such as PI and PID cause sudden changes or even impulsive surges in the command signal under external excitations by a step reference input and/or step input/output disturbances. In this paper, a simplified controller design with its preferred structure models to meet the mentioned requirements is presented for a class of minimum-phase stable linear time-invariant single-input single-output processes with proper real rational transfer function. The structure of such controller is mathematically investigated and the result is that the controller must be strictly proper and containing an integral factor. The design procedure is simple and straightforward based on reference model matching and model cancellation with only two required conditions on the desired closed-loop transfer function which are its relative degree comparing to the processes to be controlled and the equality of the lower order coefficient(s) in its numerator and denominator polynomials. A generalized integral anti-windup structure, based on back calculation method and PI/PID anti-windup scheme, to lessen the saturation effect on the integral action of the proposed controller is additionally introduced by rearranging the controller in a parallel form with one separated integral control action portion. Numerical examples are investigated to demonstrate the design procedure and verify the success of the proposed controller to the required objectives.

“…The kinetic energy of the i-th element, Ki, is given by (6), where the contribution of both center of mass linear velocity, vci, and angular velocity, ωi, of i-th element is considered with mi: mass of the element, and Ii: inertia matrix of the element with respect to its own center of mass. Term Ii is found by 7, where 0 Ri is the orientation matrix of the element as seen if the fixed coordinate system {0} given by the 3x3 submatrix [(1,1)…(3,3)] of the transformation matrix in (2); mi is the mass of the element; and i Ii is the inertia tensor in its own center of mass, as seen in its own coordinate system {i}, as seen in (8).…”

“…More recently, a direct formula is proposed in [8] for the design of a robust PID controller for sun tracker system using quadratic regulator approach with compensating pole (QRAWCP). They model the DC servo motor and the gear reducer but did not show the dynamic model of the two-axis solar system.…”

El principio de Lagrange es usado para derivar la ecuación dinámica de un Sistema Solar de Panel Solar Orientable (OSPS por sus siglas en inglés de Orientable Solar Panel System). Previo a la formulación dinámica, el análisis cinemático de facilitó mediante la consideración del sistema como un manipulador serial de cadena abierta de dos grados de libertad con dos juntas de revoluta. Los parámetros Denavit-Hartenberg permitieron encontrar la matriz de transformación para relacionar el panel solar con la tierra o bastidor. Luego, la formulación existente acerca de dinámica para manipuladores seriales fue aplicada ala sistema solar con panel orientable. El modelo dinámico explícito fue usado para construir un bloque de Simulink. Otra planta fue creada en SimMechanics. Luego, el desempeño de ambas plantas ante un mismo controlador PID fue comparado para un movimiento típico del sistema solar de panel orientable. Los resultados mostraron concordancia para ambos casos, sugiriendo que el modelo dinámico es adecuado para futuras simulaciones e implementación.
