The one or more processors receive from the sensor, a first set of torque data for the first torque of each motor of the plurality of motors, utilize the first set of torque data to determine an overall efficiency of the plurality of motors, and selectively idle at least one motor of the plurality of motors based on a result of the determination.

Systems and methods for autotuning a HVAC system controller. The method may include receiving a performance coefficient and providing a step-input using an autotuner relay to measure ultimate gain and ultimate period in a controlled HVAC system. The method may also include adjusting the ultimate gain and ultimate period to account for a relay hysteresis, and applying a tuning rule to derive a proportional gain and an integral time for a controller of the HVAC system control loop. The method may further include updating the controller with the proportional gain and integral time, and verifying the proportional gain and integral time. Verifying the proportional gain and integral time may include setting a performance envelope having a tightness related to the performance coefficient, applying a step-input to provoke a closed-loop response, and comparing the closed loop response with the performance envelope to determine whether the closed-loop response is within the envelope.

Various embodiments manage the operation of a substrate penetrating device. In one embodiment, a set of location information associated with a substrate penetrating device is received. At least one database including information associated with obstructed objects is queried based on the set of location information. A determination is made, based on the querying, that the area where the substrate penetrating device is operating includes at least one obstructed object. A probability is calculated with respect to the substrate penetrating device encountering the at least one obstructed object while operating in the area.

A vehicle control apparatus includes an electronic control unit. The electronic control unit is configured to perform feedback control of a motor such that a torque is output for stopping a crankshaft at a target angle. A first angle is used as the target angle during a first period from start of the feedback control to first detection of rotation of the crankshaft in a negative rotational direction for returning the crank angle. A second angle is used as the target angle during a second period from the lapse of the first period to detection of a changeover in a rotational direction of the crankshaft from the negative to a positive rotational direction. The electronic control unit is configured to return the target angle to the first angle at a first timing after the lapse of the second period.

Provided is a material testing machine (1) including: a load mechanism (12) that applies a load to a test object; a load measurement device that measures the load applied to the test object; and a control device (30) that performs a feedback control for the load mechanism (12) based on a deviation between a measurement value of the load and a target value of the load, in which a change in a physical quantity generated in the test object due to the load is measured, and the control device (30) includes a hunting detection unit (66) that detects hunting by comparing a frequency spectrum obtained by converting time-series data of the measurement value with a frequency spectrum obtained by converting the time-series data of the target value.

A building management system (BMS) including a controller having an adaptive interaction manager and an agent manager. The system further includes one or more input-output (I/O) devices, the I/O devices in communication with the adaptive interaction manager. The controller further including a number of BMS field devices. The I/O devices are configured to receive an input from a user, and further configured to communicate the input to the adaptive interaction manager. The agent manager is configured to determine if one or more existing software agents are capable of performing the desired action, and to automatically transmit the existing software agents to one or more of the BMS field devices based on the agent manager determining the existing software agents are capable of performing the desired action. The software agents are configured to automatically be installed in a processing circuit of the BMS field device to perform the required action.

A method includes determining control setpoints for equipment based on a time-varying availability of green energy and revenue from an incentive program of an energy provider. The method also includes controlling the equipment using the control setpoints.

A room information inferring apparatus that infers information regarding a room has an imaging unit that captures an image of a room that is to be subjected to inferring, a person detector that detects a person in an image captured by the imaging unit, and acquires a position of the person in the room, a presence map generator that generates a presence map indicating a distribution of detection points corresponding to persons detected in a plurality of images captured at different times, and an inferring unit that infers information regarding the room based on the presence map.

A sensibility meter detects biometric information relating to an operator corresponding to an output from a target appliance, and determines a comfort level of the operator based on the biometric information. A first control unit determines a second target value relating to the output based on a difference between a first target value relating to the comfort level and the comfort level. A second control unit determines a control input to the target appliance based on a difference between the second target value and the output. A δ setting unit performs weighting corresponding to an operation level of the operator, for an operation input to the target appliance by the operator, and for the control input. An adder adds the weighted operation input and control input, and inputs the resultant to the target appliance.

Aspects relate to a method for controlling a home appliance depending on a user position, along with a related system. The method includes: determining a position of a smartphone of a user; transmitting positional information on the determined position from the smartphone to a remote server; judging from the positional information whether the determined position is within or outside a predefined home zone surrounding the home appliance; generating a control signal dependent on whether the determined position is within or outside the home zone; transmitting the control signal to a control device to control the home appliance; judging from the positional information whether the determined position is within a predefined problematic zone which is outside the home zone; and reclassifying the determined position to be within the home zone or ignoring the determined position depending on at least whether the determined position is within the problematic zone.
