Leader-follower consensus control of a class of nonholonomic systems

In this paper, we propose a systematic solution to the leader-follower consensus of a class of nonholonomic chained form systems. The control design, which is reminiscent of terminal sliding mode and multi-surface sliding mode control methods, is presented to guarantee the convergence of multiple sliding surfaces, which also implies the convergence of the proposed consensus error function. On these sliding surfaces, the desired leader-follower consensus can be reached for multi-agent network formed by the nonholonomic chained form systems.

Janet Lady Clarke (1851-1909) 'Leader in the good work'

This thesis is a biographical study which examines the life and career of Janet Lady Clarke. As a leader of women's philanthrophic, health, educational and political organisations in nineteenth-century and early twentieth-century Victoria, she promoted new ideas within a conservative colonial society. Her legacies remain an integral part of Victoria's cultural heritage.

Adaptive data based neural network leader-follower control of multi-agent networks

In this paper, we propose a data based neural network leader-follower control for multi-agent networks where each agent is described by a class of high-order uncertain nonlinear systems with input perturbation. The control laws are developed using multiple-surface sliding control technique. In particular, novel set of sliding variables are proposed to guarantee leader-follower consensus on the sliding surfaces. Novel switching is proposed to overcome the unavailability of instantaneous control output from the neighbor. By utilizing RBF neural network and Fourier series to approximate the unknown functions, leader-follower consensus can be reached, under the condition that the dynamic equations of all agents are unknown. An O(n) data based algorithm is developed, using only the network’s measurable input/output data to generate the distributed virtual control laws. Simulation results demonstrate the effectiveness of the approach.

Portrait of a charismatic leader : putting Bob Brown in context

Australia has a long record of charismatic political leaders and Bob Brown is perhaps the most notable recent example, but unlike other leaders of this style he has demonstrated remarkable political skill.

Robust fault-tolerant leader-follower control of four-wheel-steering mobile robots using terminal sliding mode

This paper addresses the actuator failure compensation problem of non-linear fourwheel-steering mobile robots based on vehicle kinematics, undergoing both known and unknown failures causing degenerated steering performance or wheels stuck at some observable angles. Terminal sliding mode control technique is used to guarantee the tracking stability infinite time with the presence of actuator fault. Simulation results are given to illustrate the effectiveness of the proposed control scheme. © Institution of Engineers Australia 2012.

The emotional labour of the aspirant leader: traversing school politics

The emotions of the aspirant leader are underexplored. In this chapter, we detail how aspirants experience the transition from teacher to leader and report on the kinds of emotional labour associated with the transition. This was examined during events of high emotional arousal for 130 school aspirants: when they felt professionally wounded, either by colleagues, leaders, parents or students. During a time of wounding, emotional work and emotional labour hinged on the dissonance between 'display rules' of the school and what aspirants' actually felt. Exploring the wounding stories revealed common display rules, which were often broken. Breaking these rules always had consequences and emotional correlates. The most prevalent form of emotional labour was surface acting. The.final discovery was the resilience of the aspirants as they recovered. Invariably, aspirants progressed through an emotion cycle of Regrouping, Recovery and Resolution. The quality of collegial relationships was the key to resolving the woundings.

The effects of leader-member exchange and employee wellbeing towards employee turnover intention

 Research studies the role of employee wellbeing in relationship of LMX and turnover intention. Academicians from the community colleges, Malaysia were the respondents and structural equation modelling (SEM) was used. Results indicated that LMX is significantly predicts turnover intention and revealed the relationship between LMX and turnover intention decreases when factor on employee wellbeing is amended.

The role of the educational leader in long day care – how do they perceive their role?

National reforms introduced into the early childhood education and care sector across Australia have created a requirement for each service to appoint an ‘educational’ leader to provide curriculum direction to ensure that children achieve quality care and education to lead to positive outcomes. Leadership in the early childhood has often been contested and complex, but the addition of a new leadership for building pedagogy and practice has created additional complexities. This paper reports the findings of a small-scale qualitative research study investigating how a small number of educational leaders working in long day care settings in urban Australia perceive their role. The study identified that these educational leaders came to the position unwillingly and felt poorly prepared and supported to meet the challenges presented.

Transformational leadership and the work outcomes of Chinese migrant workers: The mediating effects of identification with leader

This study examines the mediating influence of identification with leader on the relationship between follower perceptions of transformational leadership behavior and their work outcomes, using data obtained from migrant workers and their supervisors in a large manufacturing company located in south-eastern China. Hierarchical regression analysis revealed that transformational leadership was positively related to the affective commitment and job performance of followers, and negatively related to their turnover intentions. In contrast, no significant influence was found of transformational leadership on the innovative behavior of followers. Subsequent analysis revealed that identification with leader mediated the relationship between transformational leadership and follower attitudes, but did not mediate the relationship between transformational leadership and follower job performance. These findings highlight the importance of cultural and wider contextual influences on the processes by which leadership impacts on the work outcomes of migrant workers in the Chinese manufacturing industry. The managerial implications of these findings are discussed and suggestions for future research provided.
