A third number describes the effect of other movements on the robot\u2019s balance. This model gives rise to a simple preview balance controller consisting of a four-term control law with easily calculated gains and a reverse-time low-pass filter acting on a preview of the command signal. The filter makes the robot lean in anticipation of future movements. Simulation results are presented showing the balance controller achieving excellent tracking of large fast motion commands while simultaneously maintaining the robot\u2019s balance and accurately rejecting disturbances caused by other motions being performed by the robot. The controller is also robust to effects such as actuator saturation and sensor noise. <\/jats:p>","DOI":"10.1177\/0278364917691114","type":"journal-article","created":{"date-parts":[[2017,2,9]],"date-time":"2017-02-09T13:47:45Z","timestamp":1486648065000},"page":"1489-1507","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":31,"title":["A simple model of balancing in the plane and a simple preview balance controller"],"prefix":"10.1177","volume":"36","author":[{"given":"Roy","family":"Featherstone","sequence":"first","affiliation":[{"name":"Department of Advanced Robotics, Istituto Italiano di Tecnologia, Genova, Italy"}]}],"member":"179","published-online":{"date-parts":[[2017,2,9]]},"reference":[{"key":"bibr1-0278364917691114","doi-asserted-by":"publisher","DOI":"10.1115\/1.3426525"},{"key":"bibr2-0278364917691114","doi-asserted-by":"crossref","unstructured":"Azad M (2014) Balancing and Hopping Motion Control Algorithms for an Under-actuated Robot.
