The 48-year-old has endured a difficult spell since becoming the west London outfit’s majority stakeholder in August 2011.
The new Hoops boss registered his first victory against Fulham on Saturday to lift QPR off the bottom of the table.
But Fernandes insists he will not leave his position, irrespective of the club’s status next May.
“Come what may, in May, we’ll still be here,” he told QPR’s website.
“I’m firmly committed to the club. I’m not someone who’s going to run away from things.
“There are still a lot of good things happening. The training ground is well on track and the stadium plans are progressing. We’re hopeful of getting category two status in the academy.
“There’s no change to our off-the-field strategy. There are lots of good things going on.”
He added: “We inherited a club that needed a hell of a lot of work and we’ll continue to progress with our short, medium and long term goals.
“I’m a strong character who has been through a hell of a lot in life. The aviation business isn’t for those with a weak heart.
“But I’ve got to say, the run of results – before Harry came in – really affected me. It’s been really tough.
“I’m the leader and it’s a great shame that after so much honest effort we’re where we are in the table.”
