For the comfort of the driver and passengers, the output constraint for the yaw acceleration is chosen as 0.4g/[l.sub.c]; that is,
Figure 8 shows the vehicle's yaw acceleration at [mu] = 0.8 and an entry speed of 20km/hr.
is added mass of platform in the surge due to a unit yaw acceleration. [N.sub.v].
where m is the total mass of the vehicle, the lengths a and b are defined as shown in Figure 1(a), [a.sub.y] is the lateral acceleration, [[??].sub.r] is the yaw acceleration, and [I.sub.z] is the yaw moment of the vehicle inertia.
There was a significant reduction in average yaw acceleration in the 250-ms delay condition as compared with the 125-ms delay condition.
"During this period of intense mental activity the commander did not detect changes to the aircraft's motion and in particular the yaw acceleration (swinging from side to side)."
''During this period of intense mental activity, the commander did not detect changes to the aircraft's motion and in particular the yaw acceleration (sideways movement).
Yaw acceleration caii be determined from the lateral acceleration measurements.
Furthermore, this strategy is based on yaw acceleration detection and electromagnetic proportional control technology to realize the additional yaw moment compensation because of its good cost performance and adaptability for hydraulic control system.
The FIS module we propose uses five vehicle signals steering wheel angle (SWA), steering wheel rate (SWRATE), yaw rate (AVZ), yaw acceleration (AAZ), and lateral jerk (AAY).
The detection stage constantly monitors the five vehicle signals: steering wheel angle (SWA), steering wheel rate (SWRATE), yaw rate (AVZ), yaw acceleration (AAZ), and lateral jerk (AAY) and feeds them to the fuzzy OS/US detection module.The model-free fuzzy inference system (FIS) uses the incoming signals to determine the current state of the vehicle.
It is generally assumed that as any lateral or yaw accelerations are sensed a driver will be able to provide an adequate counter response to a gust to prevent a significant deviation.
