reward error during training

Hello,

Im using reinforcemet designer to train my model,

and here is my problem.

Q. I dont not why my reward cannot go up to 0.1, why is this happen?? How can I fix this??

Hi @기범

In Reinforcement Learning (RL), the reward is a signal that guides the agent’s learning by providing feedback on its actions. It changes dynamically based on the agent’s behavior and the environment’s response. A well-designed reward function encourages desired actions and discourages unwanted ones, leading to improved performance over time.

You can try the following to improve your performance:

• Ensure that “cos(psi(t)) - cos(psi(t-1)) > 0” is met frequently by checking if psi(t) increases over time.
• Verify that the initial conditions of the delay block are properly set to prevent incorrect first-step evaluations.
• Modify the reward function threshold to make the positive reward condition more lenient.
