24. Rule Controller example

First, we import all the necessary libraries. Remember to always import sinergym, even if it appears unused, as it’s needed to define the environments.

[1]:

from typing import List, Any, Sequence
from sinergym.utils.constants import YEAR
from datetime import datetime
import gymnasium as gym
import numpy as np
import sinergym

Next, we can define the environment we want to use. In this case, we’re using the Eplus demo.

[2]:

env = gym.make('Eplus-5zone-hot-continuous-v1')

[ENVIRONMENT] (INFO) : Environment 5zone-hot-discrete-v1 created successfully.

For the Rule-based controller, check out the already defined controllers. There’s one for each building. Since the demo is based on the 5Zone building, we’re extending that controller and defining the action function we want. Feel free to modify the function to define your own action.

[3]:

from sinergym.utils.controllers import RBC5Zone

class MyRuleBasedController(RBC5Zone):

    def act(self, observation: List[Any]) -> Sequence[Any]:
        """Select action based on outdoor air drybulb temperature and daytime.

        Args:
            observation (List[Any]): Perceived observation.

        Returns:
            Sequence[Any]: Action chosen.
        """
        obs_dict = dict(zip(self.env.get_wrapper_attr('observation_variables'), observation))

        out_temp = obs_dict['outdoor_temperature']

        day = int(obs_dict['day_of_month'])
        month = int(obs_dict['month'])
        hour = int(obs_dict['hour'])
        year = int(obs_dict['year'] if obs_dict.get('year',False) else YEAR)

        summer_start_date = datetime(year, 6, 1)
        summer_final_date = datetime(year, 9, 30)

        current_dt = datetime(year, month, day)

        # Get season comfort range
        if current_dt >= summer_start_date and current_dt <= summer_final_date:
            season_comfort_range = self.setpoints_summer
        else:
            season_comfort_range = self.setpoints_summer
        season_comfort_range = self.setpoints_winter
        # Update setpoints
        in_temp = obs_dict['air_temperature']

        current_heat_setpoint = obs_dict[
            'htg_setpoint']
        current_cool_setpoint = obs_dict[
            'clg_setpoint']

        new_heat_setpoint = current_heat_setpoint
        new_cool_setpoint = current_cool_setpoint

        if in_temp < season_comfort_range[0]:
            new_heat_setpoint = current_heat_setpoint + 1
            new_cool_setpoint = current_cool_setpoint + 1
        elif in_temp > season_comfort_range[1]:
            new_cool_setpoint = current_cool_setpoint - 1
            new_heat_setpoint = current_heat_setpoint - 1

        #Clip setpoints to the action space
        if new_heat_setpoint>self.env.get_wrapper_attr('action_space').high[0]:
            new_heat_setpoint=self.env.get_wrapper_attr('action_space').high[0]
        if new_heat_setpoint<self.env.get_wrapper_attr('action_space').low[0]:
            new_heat_setpoint=self.env.get_wrapper_attr('action_space').low[0]
        if new_cool_setpoint>self.env.get_wrapper_attr('action_space').high[1]:
            new_cool_setpoint=self.env.get_wrapper_attr('action_space').high[1]
        if new_cool_setpoint<self.env.get_wrapper_attr('action_space').low[1]:
            new_cool_setpoint=self.env.get_wrapper_attr('action_space').low[1]

        action = (new_heat_setpoint, new_cool_setpoint)
        if current_dt.weekday() > 5 or hour in range(22, 6):
            #weekend or night
            action = (18.33, 23.33)

        return action

Now that our controller is ready, we can use it:

[4]:

# create rule-based controller
agent = MyRuleBasedController(env)

for i in range(1):
    obs, info = env.reset()
    rewards = []
    truncated = terminated = False
    current_month = 0
while not (terminated or truncated):
    action = agent.act(obs)
    obs, reward, terminated, truncated, info = env.step(action)
    rewards.append(reward)
    if info['month'] != current_month:  # display results every month
        current_month = info['month']
        print('Reward: ', sum(rewards), info)
print(
    'Episode ',
    i,
    'Mean reward: ',
    np.mean(rewards),
    'Cumulative reward: ',
    sum(rewards))
