“…The complexity can be significantly reduced for a few operating points with bumpless-transfer controllers, which have appeared in the literature as an ad-hoc adaptive control scheme [13], [14], [15], [16], [17]. The approach is less conservative, easier to synthesize, and easier to implement than a polytopic controller or other interpolation scheme [18] [19], and has a larger operating range than a nominal controller [20], [21]. For example, if an inverter is connected to a microgrid with an equivalent impedance that is much less than anticipated by the designer, then the inverter with a nominal controller will exhibit an unstable response as shown in Figure 2 and the inverter with a bumpless controller will exhibit a stable response as shown in Figure 3.…”

“…Possible large deviations from the mean values, together with the hybrid architecture of the thermal controller may cause discontinuities in the control signals. To handle these discontinuities suitable management policies and procedures has been developed, like ramp filters and hysteresis switching techniques [13].…”

“…Hay trabajos que extienden o combinan algunas de las técnicas ya propuestas, como (Zhang et al, 2005) que combina la técnica de seguimiento de Graebe and Ahlén (1996) con el método de acondicionamiento de la referencia de Hanus et al (1987). En Pasamontes et al (2010) se analizan diferentes técnicas BT mostrando las ventajas e inconvenientes de cada una de ellas dependiendo de la naturaleza del problema que se trate de resolver. En él, concluyen que el método de seguimiento al control activo es adecuado cuando el tiempo entre conmutaciones es suficientemente grande como para que se alcance el estado estacionario o la señal del controlador latente alcance al activo.…”

“…Aunque se implementa para el controlador PID, el diseño puede aplicarse a cualquier tipo de controlador, no siendo exclusivo para controladores con acción integral. El principal inconveniente que presenta es que requiere la implementación y ejecución paralela de un conjunto de controladores, lo que aumenta la demanda computacional a medida que aumenta el número de controladores (Pasamontes et al, 2010). Para reducir dicho coste, se plantea el diseño del supervisor utilizando técnicas de transformación de modelos, identificando los modos candidatos a conmutación que serán los únicos que ejecuten controladores de seguimiento.…”
