“…The absence of measurements in future instants of time (i>0) is modeled with delta functions [17,19,20], a MR technique for time-varying models that modifies the Kalman gain indicating the presence ( i =I) or absence ( i =0) of measurements in every estimation instant. The choice of the filter to be used depends on the kinematic model associated to the object.…”

“…The Potential Field Projection method (PFP) combines the PF method [3] with the multi-rate Kalman filter (MR-KF) estimation [19,20], thus considering present and future vehicle and obstacles locations within the planning strategy. Moreover, the original concept of the PF method [3] for motion generation was reintroduced, in the sense that artificial forces determine the vehicle acceleration.…”

“…In the present study, the BTD technique is evaluated through a predictive PF path planning method described in [23][24][25], the Potential Field Projection method. This method is based on the combination of the classical Potential Fields method [22] and the multi-rate Kalman filter estimation [26,27] and takes into account the uncertainties on locations, the future trajectories of the robot and the obstacles and the multi-rate information supplied by sensors. The particularities of this approach are described in this section.…”

“…The main idea consists in filling the robot's workspace with an artificial potential field in which the robot is attracted by the goal and repelled by the obstacles. In this research field, a considerable amount of variants and improvements have [22] and the multi-rate Kalman filter estimation [26,27] and takes into account the object volume, the uncertainties on locations, the future trajectories of the robot and the obstacles and the multi-rate information supplied by sensors. An initial path is obtained by means of the PFP method, taking into account the attractive forces produced by the goal in the present and future instants of time.…”

“…Más recientemente se han publicado trabajos donde se analiza el control multifrecuencia H ∞ [51], el controlóptimo multifrecuencia [67], el control predictivo con muestreo no convencional [62] e incluso su extensión a sistemas no lineales [22]. En trabajos como [34,53,54,68] se aborda el caso de muestreo asíncrono multifrecuencia, en el que las mediciones siguen una pauta periódica, pero el instante de medición no es síncrono con la actualización de la entrada.…”
