ThermalBurstScenario

Robotics scenarios · Implementation: mlsysim/engine/scenario_definitions/robotics/plant.py.

Construct this scenario with keyword inputs. The fields below show the types and defaults declared by this class.

A burst_factor times rated-current burst in joint, first-order lumped, fixed resistance.

Notes

Equation: Compose mlsysim.physics.motors.calc_first_order_temperature, mlsysim.solvers.ThermalBurstModel.

Assumptions: The winding is a first-order lumped thermal body with fixed resistance during each burst.

Excludes: Spatial gradients, resistance-temperature feedback, and unmodeled cooling changes are absent.

References

Derivation: this scenario binds its input fields to the referenced implementation contracts: mlsysim.physics.motors.calc_first_order_temperature, mlsysim.solvers.ThermalBurstModel. The methods below identify any additional arithmetic.

Examples

>>> from mlsysim import Scenarios

Name Description
temperature Winding temperature after an elapsed constant-current burst from start. Equation:

temperature

engine.scenario_types.ThermalBurstScenario.temperature(elapsed, start)

Winding temperature after an elapsed constant-current burst from start. Equation: mlsysim.physics.motors.calc_first_order_temperature using the result’s asymptote and time constant. Units: temperature; resistance and lumped thermal parameters remain fixed.

result

engine.scenario_types.ThermalBurstScenario.result

Evaluate this scenario through mlsysim.solvers.ThermalBurstModel.solve. Equation: pass the stated fields to that implementation; its contract defines the calculation and feasibility tests. Units: each returned field follows the referenced result schema; no independent equation is evaluated by this wrapper.
