Ardley's side have dropped to 21st in the league table with three consecutive defeats, leaving the Dons two points from relegation.
With just three games remaining, Ardley has issued a rallying call to fans to help guide the team to safety.
He told the club's official website: "People would not be human if they did not get butterflies in their stomachs about what might happen.
"We have to turn those nerves into positivity. We need to push that negativity aside.
"I am staying positive and I believe the players are too. I will lead them and I want the fans to come on board too.
"Together, I believe we can be a potent force. The fans can help us get over the line. We can all be heroes."
