The control signal consists of: an equivalent control to assign the desired dynamics to the closed-loop system, a switching control to guarantee a sliding mode, and a fuzzy control to enhance fast tracking and to attenuate chattering. Sufficient conditions for asymptotic tracking are achieved when matching conditions are satisfied. The control method is applied to the position control of an electrohydraulic servo system. To verify the potential and effectiveness of the proposed controller, simulation results are given to demonstrate its strong robustness against a large range of parameter variations, load disturbance and nonlinear spring stiffness.","PeriodicalId":394492,"journal":{"name":"1998 Second International Conference.

The GA employs the variable penalties and the criterion of unfeasible chromosomes for improved evaluation function and improved arithmetic crossover. As a result, the improved GA increases the search efficiency in the solution space. We discuss the efficiency by comparing the proposed GA with traditional simple GA (SGA).","PeriodicalId":394492,"journal":{"name":"1998 Second International Conference.

Because fuzzy arithmetic automatically leads to monotonic increasing outputs a direct fuzzification of the backpropagation method does not work.

Furthermore we can show that for the proposed method convergence can be guaranteed.","PeriodicalId":394492,"journal":{"name":"1998 Second International Conference.

The need to implement vision tasks in parallel arises from the speed requirements of real-time environments in various application domains. In this paper we propose that a distributed computer system can be utilised to replace the specialised machine for the parallel implementation of vision tasks. We introduce some techniques used in distributed systems and adopt a divide-and-conquer policy to schedule the complex vision tasks for parallelism. Two traditional vision algorithms for matrix operation and image matching are implemented using PVM (parallel virtual machine). Furthermore, a hierarchical object recognition system is described as an example of parallelism on distributed systems. Finally we conclude that some vision tasks can be realised on a general distributed system to achieve the speedup at a low cost.","PeriodicalId":394492,"journal":{"name":"1998 Second International Conference.

To satisfy this aim, an internal cognitive space, called a metamorphic internal image space, is introduced. The metamorphic internal image space is a space that integrates the sensory inputs and the temporal change of the space, so that the agent is able to behave by relying only on the image. An agent with the metamorphic internal image is considered to have following two major characteristics: 1) it can learn the chain of actions considered as a behavior; and 2) it can move with/without the change of sensory input pattern. A learning mechanism based on a multi-agent system is introduced for the realization of the metamorphic internal image. The behavior of the multi-agent system can be regarded as a complex system. Computational experiments show the emergent behavior of the mobile agent with metamorphic internal image based on the complex learning system.","PeriodicalId":394492,"journal":{"name":"1998 Second International Conference.
