pcgym 0.0.7

Reinforcement learning suite of process control problems.

Reinforcement learning environments for process control

Quick start ⚡

Setup a CSTR environment with a setpoint change

# Setpoint
SP = {'Ca': [0.85 for i in range(int(nsteps/2))] + [0.9 for i in range(int(nsteps/2))]} 

# Action and observation Space
action_space = {'low': np.array([295]), 'high': np.array([302])}
observation_space = {'low': np.array([0.7,300,0.8]),'high': np.array([1,350,0.9])}

# Construct the environment parameter dictionary
env_params = {
    'N': nsteps, # Number of time steps
    'tsim':T, # Simulation Time
    'SP' :SP, 
    'o_space' : observation_space, 
    'a_space' : action_space, 
    'x0': np.array([0.8, 330, 0.8]), # Initial conditions [Ca, T, Ca_SP]
    'model': 'cstr_ode', # Select the model
}

# Create environment
env = pcgym.make_env(env_params)

# Reset the environment
obs, state = env.reset()

# Sample a random action
action = env.action_space.sample()

# Perform a step in the environment
obs, rew, done, term, info = env.step(action)
