The automatic analog determination of human transfer function coefficients

Understanding and Modeling the Human Driver

“…The principal roots of driver modeling as it relates to these control activities extend back to the early years of human-machine and aircraft pilot studies [1][2][3][4][5][6][7][8][9][10][11][12][13][14]. Those studies helped to reveal various properties unique to, or characteristic of, the human as a controller of dynamical plants [1,4,8,14,15] and certain vehicles [6,[16][17][18][19][20]. For example, in 1961 Ornstein [8] proposed the following transfer function, H(s), model of the human operator for pursuit-type manual tracking tasks,…”

Models for Force Control in Telesurgical Robot Systems

“…The coefficient values are determined by taking some physical attributes into account, such as velocity or static gain [18]. Due to the relatively high number of parameters, this model can become rather sophisticated, allowing one to describe neuromuscular effects or other dynamic response characteristics [19].…”

Mathematical models of human operators in simple two-axis manual control systems

“…R T HE USE OF mathematical models for the descrip tion of human tracking behavior has been re stricted almost exclusively to the study of singleaxis manual control. This has been true of the three major approaches to modeling of human operator per formance, i.e., the spectral-analysis approach [1], [2], multiple-regression analysis using orthonormal filters [3], and the parameter tracking or model-matching technique [4]- [6]. All three methods have been generally successful in obtaining mathematical descriptions of the human operator's input-output behavior in both com pensatory and pursuit tracking tasks when the forcing function bandwidth was sufficiently restricted and control I960 element dynamics were generally no higher than third order.…”
