Design method for a controller of a distance learning calligraphy system via public networks

By using a distance learning calligraphy system, a student can learn calligraphy skills as if in the presence of a teacher. In order to develop such a system, we adopt a master-slave system via public networks and propose a design method for its controller. This method satisfies the following two requirements: a) the stability of the system can be guaranteed for any transmission delay due to the public network, and b) the master controller can be designed independently of the slave controller. The validity of the proposed design method is confirmed by simulation results. Experimental results indicate the performance of the distance learning calligraphy system developed using the controllers designed via the proposed method.
