Re: Control system response time and bandwidth?

my primary reason for needing these timing specs is for using closed loop control with the RC - I need to get a handle of how fast sensor inputs make it to the actual input variables, and how long it takes from the time the code sets a PWM variable until the affected motor actually sees the change across its terminals.

Im also curious about the entire system response time, from the joysticks to the motor terminals to get a idea of how quick the robot will respond to driver commands. I measured it last year with the old control system and it was surprizingly slow -if you watched the voltage on the victor outputs with a scope, and bumped the joystick, the delay was very noticable - from the top of my head I think it was at least half a second, maybe longer.
