“…Remark 1: The gain-scheduled control scheme has been successfully proposed by [14] to design fuzzy controller for stabilizing the fuzzy systems. Because the fuzzy system is structured by multiple models, the basic concept of the control scheme can be also applied to establish the gain-scheduled controller (12) for LPV systems. However, comparing (12) with fuzzy controller of [14], one can find that the structures of fuzzy controller of [14] and the proposed controller (12) are different.…”

“…It is less conservative than the conditions (6) because the Lyapunov function applied in Theorem 2 possesses several positive definite matrices but single matrix. Via finding the feasible solutions of the conditions (14), the gain-scheduled controller (12) can be designed to guarantee the asymptotical stability of the closed-loop system (13) in the mean square. In the next section, the simulation results are proposed to demonstrate the effectiveness and usefulness of the proposed design methods.…”

In this paper, two technologies to design gain-scheduled controller are proposed for discretetime Linear Parameter Varying (LPV) systems with multiplicative noises. In the considered systems, the time-varying parameters are proposed to describe the uncertainties. And, the added multiplicative noise term is applied to describe the stochastic behaviors of the system. Furthermore, the gainscheduled design scheme is applied to deal with the stabilization problem of the LPV systems with multiplicative noises. Through the parameter-independent and parameter-dependent Lyapunov functions, the corresponding sufficient conditions are derived to discuss the stability and stabilization problems of the system. In order to apply the convex optimization algorithm, the derived sufficient conditions are converted into Linear Matrix Inequality (LMI) problems. Based on the proposed design technologies, gain-scheduled controllers are designed such that the considered system is asymptotically stable in the mean square. Finally, two numerical examples are applied to demonstrate the application and effectiveness of the proposed design technologies of this paper.

“…The PI gains determine the closed-loop performance and were designed to meet the specification described in the frequency domain under a given operating condition. Thus, an additional gain-scheduling algorithm as in [9] should be embedded in the control algorithm to achieve a satisfactory closed-loop performance under several operating conditions. A feed-forward compensation technique was proposed to eliminate disturbances by the back electromotive force (EMF) effect, which is interpreted as the feedback-linearization (FL) technique in the control theoretical perspective [10,11].…”

This article presents a robust speed tracking algorithm for a permanent magnet synchronous generator utilized for wind power generation systems, considering the machine parameter and load uncertainties. There are two major contributions: (a) a disturbance observer is designed to exponentially estimate disturbances from the model-plant mismatches and severe load torque variations, and (b) it is included in a nonlinear cascade-type proportional speed tracking controller to establish the performance recovery and offset-free properties without the use of tracking error integrators. A simulation result numerically verifies the effectiveness of the proposed technique, where the PowerSIM software emulates a wind power generation system.

“…Con esto se puede diseñar una familia de controladores no lineales, lo que se conoce como ganancias programadas (gain-scheduling) (Khalil, 1996). Esta técnica ha demostrado su efectividad en sistemas electromecánicos (Béjar y Ollero, 2008; Moriano y Naranjo, 2012) y en motores de corriente directa (Matausek et al, 1996;Kukolj et al, 1999).…”

ResumenEn este artículo se presenta un esquema de control para una máquina utilizada para fabricación de películas delgadas, con un motor de corriente directa sin escobillas, basada en el método de centrifugación. Se incluye el modelo no lineal del motor sin escobillas, que corresponde a una máquina síncrona trifásica, con los flujos del rotor y las corrientes en el estator, como las dinámicas eléctricas, además de la velocidad en el rotor, como la dinámica mecánica. El objetivo de control es la regulación de la velocidad del rotor. Se utilizó la técnica de control por bloques y así obtener una variedad deslizante. Se eligió la técnica de control por modos deslizantes para garantizar que la variedad elegida sea atractiva y obtener robustez en lazo cerrado. Para completar el esquema de control se incluye un observador para estimar los estados no medibles, en este caso, los flujos del rotor. Se implementó el esquema de control propuesto en la máquina para fabricación de películas delgadas, además de un controlador basado en un PID con ganancias programadas, lo anterior para realizar la comparación de ambas técnicas. El esquema de control por modos deslizantes propuesto presenta ventajas sobre el controlador PID, ya que se obtiene la regulación de la velocidad del rotor, sin error en estado estacionario, considerando variaciones paramétricas. Palabras Clave:Modos deslizantes, Sistema no lineal, Motor sin escobillas, Controlador PID. IntroducciónUna de las principales técnicas para la obtención de películas delgadas es el método de centrifugación o spin-coating, utilizado para depositar soluciones en sustratos planos, en general, hechos de vidrio. El procedimiento consta de cuatro partes: 1) depósito, 2) aceleración, 3) velocidad constante, y 4) evaporación. En la etapa de depósito, una cantidad determinada de una solución, compuesta de un material mezclado con solvente en una proporción conocida, se vierte en el centro del sustrato. De acuerdo a las necesidades del usuario, el sustrato puede tener diferentes dimensiones; se coloca en el centro de una base giratoria y se sujeta mediante algún adhesivo o una bomba de vacío, siendo el segundo método el más utilizado por su practicidad y seguridad (Tyona, 2013).En la etapa de depósito, el sustrato puede estar en reposo o girando con baja velocidad, típicamente 500 RPM. En la segunda etapa, aceleración, se incrementa la velocidad angular del sustrato hasta alcanzar la velocidad requerida. Una vez que se alcanza la velocidad requerida, inicia la etapa de velocidad constante, el usuario selecciona su duración. La velocidad angular puede alcanzar hasta las 10,000 RPM y debe ser controlada con alta precisión, sin variaciones, para lograr la uniformidad y calidad adecuada en la película y garantizar repetitividad en los resultados.Se pueden requerir varias etapas de aceleración y velocidad constante. La evaporación ocurre durante todo el proceso y se puede utilizar tratamiento térmico para retirar el exceso de solvente. Entonces, la máquina para spin coating, llamado spincoa...
