Physical Systems

Available Physical Systems:

Supply Converter Motor Load System (SCML)

Physical System Base Class

class gym_electric_motor.core.PhysicalSystem(action_space, state_space, state_names, tau)[source]

The Physical System module encapsulates the physical model of the system as well as the simulation from one step to the next.

Parameters:

action_space (gymnasium.Space) – The set of allowed actions on the system.
state_space (gymnasium.Space) – The set of possible systems states.
state_names (ndarray(str)) – The names of the systems states
tau (float) – The systems simulation time interval.

property action_space: Returns: gymnasium.Space: An Farama Gymnasium Space that describes the possible actions on the system.

close()[source]: Called, when the environment is closed. Close the System and all of its submodules by closing files, saving logs etc.

property k: Returns: int: The current systems time step k.

property limits: Returns: ndarray(float): An array containing the maximum allowed physical values for each state variable.

property nominal_state: Returns: ndarray(float): An array containing the nominal values for each state variable.

reset(initial_state=None)[source]

Reset the physical system to an initial state before a new episode starts.

Returns:: The initial systems state
Return type:: element of state_space

simulate(action)[source]

Simulation of the Physical System for one time step with the input action. This method is called in the environment in every step to update the systems state.

Parameters:: action (element of action_space) – The action to play on the system for the next time step.
Returns:: The systems state after the action was applied.
Return type:: element of state_space

property state_names: Returns: ndarray(str): Array containing the names of the systems states.

property state_positions: Returns: dict(int): Dictionary mapping the state names to its positions in the state arrays

property state_space: Returns: gymnasium.Space: An Farama Gymnasium Space that describes the possible states of the system.

property unwrapped

Returns this instance of the physical system.

If the system is wrapped into multiple PhysicalSystemWrappers this property returns directly the innermost system.
