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 closed-loop control device for a process, in which a dead band element is connected upstream of a linear dynamic controller to reduce actuating interventions in the steady control state. If a control deviation (e) of the control loop exceeds a first threshold value (s1), then the dead band element is automatically deactivated, where a control deviation (e1) passed via the dead band element is uninfluenced by a set dead band in the inactive state. If the control deviation (e) then undershoots a second threshold value that is less than the first threshold value, then the dead band element is automatically re-activated. This reduces the energy consumption and wear of an actuator and improves the control behavior with regard to steady-state accuracy and the control behavior of the control loop.

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.
摘要:
Method, article of manufacture and system using minimum data to determine whether a sliding-mode control should be applied in a plant. First measure the plant in an open-loop control fashion, and using the measured data, describe a state equation of the plant by system identification and order determination methods. Then design a switching hyperplane for sliding-mode control. Next, calculate higher order statistics on the difference between an output of a linear model on the hyperplane and an output of the sliding-mode control model in the measured data; When any of the higher order moments is larger than a predetermined threshold, configure a controller as a sum of the linear control input term and the nonlinear control input term. If both higher-order moments are smaller than the threshold, then configure the controller using only a linear control input term.
