Setup & Helper functions ¶įirst let's set up some helper functions for loading data and plotting. This has the effect of trying to move gforce to 1.0, matching the gravitational force.

There you will find details about commands and how to use them. Where thrott is the throttle percentage from 0 to 1 or no thrust to full thrust. Once you know how kOS generally works the wiki is really the most important site.
#Kerbal space program kos update#
As a first step for hovering, we'll have our controller change in velocity by limiting our g force to 0 via $gforce$ is our onboard gravitational acceleration magnitude using our graviola detector.Īnd in the running controller loop, we update $thrott = thrott + \Delta thrott$ SET thrott to thrott + dthrott. Towards this, we're going to implement, you guessed it, a PID controller. Our intrepid little spaceship consists of a single engine, some landing legs and a parachute in case (when) our controller goes haywire. So we're going to try and write a kOS script for Kerbal Space Program (KSP) to control a single-stage rocket engine to hover at a set altitude. Kerbal Space Program kOS Hover PID planner ¶
