If they didn't put your name in all caps or something, you're good to go. Just walk up to the judge and explain during court. Ignore the bailiff, he won't tackle you.
"Disobeying an officer" should not be a crime. They can, and do, make illegal demands. For example, insisting that you are required to provide ID when you are not (as one of the less harmful but more common examples) and then arresting (and/or assaulting) you when you refuse or don't have it on you.
Should be. Unfortunately, the Supreme Court ruled that an officer doesn't have to know the law to enforce it, implying that you as a citizen will get in trouble if an officer tells you to do something as long as he thinks he's enforcing a law.
These days, the only thing you can do with any reliability is exercise your right to a lawyer. Even then, you had better hope the officer isn't having a bad day, because there's no repercussion for him for just arresting you then and there.
And, though they are not supposed to, police consider it to be evidence of guilt if you request an attorney, especially without first giving into their questions/interrogations without counsel.
