There is a similar thread about this here:
http://squidboards.com/threads/what-is-the-meta-objective-of-tower-control.3182/
That thread has tons of good posts/tips on it, but i'll give you a quick overview.
-Don't always go for the knockout, sometimes the best way to win is just prevent them from beating your score.
-Since you main Dynamo, I highly suggest never getting on the tower unless absolutely necessary. Your job should really be covering turf around the tower to prevent ambushes. Defensive play is probably your best option.
-That being said, if you desperately need to get the lead, jump on the tower regardless of what is happening. It is better for your team to constantly die as someone pushes the tower 1-3 points to get the lead, then not get on the tower and lose. If your entire team dies on the enemies side of the map, it's okay because they can't push the tower fast enough to really take advantage of the situation.
-Generally you want to play more offensive weapons in Solo Queue, as you can't really afford to get a super defensive team. Since you also main the Tentatek, I would suggest using this more often than your Dynamo. Unlike Splat Zones you can directly carry a team to victory. You can have an awful team in Tower Control and still win because you got the kills necessary to make a push. If you find the Tentatek isn't work I suggest using a Blaster/shorter ranged Roller.
-With all gamemodes, territory control is key. Always, ALWAYS cover turf around the tower. Even when the Tower is in neutral, make sure you cover the turf in front of the path before you push.
-Unlike almost every other gamemode, you want to Super Jump in this mode. Why? Because as stated previously getting 1-3 points for your team can make the difference that you need to gain the lead.
-Don't be dumb, avoid pushing the tower unless you have at least a 1 man advantange, but really you should get a 2 man advantage.
-Something a lot of people don't use: You don't have to ride the tower back to the middle, all you have to do is get on it once and get off for it to move back. Often times people don't do this, and it's painful when they get shot down because they rode the tower to mid. You can see if your enemy does this by looking at the tower icon (where it shows the scores) to see if the enemy is riding the tower. If they aren't, you don't have to shoot on the tower cautiously when the tower is returning to mid from their side.
