Abstract: In a method for failure, detection, operational data from a plurality of components in a system are received. A bank of submodels is created based on the operational data. The bank of submodels corresponds to a normal mode and one or more faulty modes of the system and is valid in different operating regimes of the system. Each of the banks of submodels has a respective weight (validity) and a respective suboutput. An output of the system is a weighted sum of the suboutputs of the submodels. The operational data is therefore processed to generate a validity profile through a constrained Kalman Filter (KCF) based multimodel fault detection and diagnosis (FDD). Subsequently, the validity profile is output. The validity profile is indicative of an operation state of the system at a given time, and the operation state includes a normal state and a fault state.

Abstract: A pneumatic valve system that includes an actuator that pneumatically actuates a valve, and circuitry that calculates a control signal to control the actuator by compensating for nonlinear dynamic of the actuator using a stable inverse model of the valve, optimizes parameters of the stable inverse model such that a difference between output information of the pneumatic valve system and desired reference information is reduced, and outputs the control signal to control the actuator.

Abstract: Obstacle avoidance by a remote or autonomously operated vehicle, such as an unmanned aerial vehicle (UAV), is of critical importance. By utilizing a monocular camera, a UAV may capture an image and select a middle sub-image for processing. If the average depth of the pixels in the middle sub-image is greater than a previously determined threshold, the UAV may proceed forward. However, if the average depth of the pixels is less than the threshold, a turn is required. A left sub-image and a right sub-image are processed and, based on the one having the greatest depth, a turn instruction is provided to the UAV.

Abstract: A method of determining a fouling location of a shell and tube heat exchanger is provided. Under the method, a simulation model of the heat exchanger is partitioned into multiple segments. Each segment corresponds to a different one of multiple operating scenarios of the heat exchanger. For each operating scenario, temperature data and pressure drop data are generated from the simulation model of the heat exchanger. The fouling location of the heat exchanger corresponds to a respective segment in each of the multiple operating scenarios. The temperature data and the pressure drop data are classified based on the multiple segments of the simulation model by inputting the temperature data and the pressure drop data to one or more machine learning classification algorithms. The fouling location and a value of accumulated fouling at the fouling location are determined based on the classified temperature data and the classified pressure drop data.
