To study the sta.ility of the feedba.k control, the concept of frozen system is used. The controller design a.ms to ensure tha. the system is sta.le when the bea. stops a. a.y length within the motion ra.ge. Lya.punov’s theorem is used to find the sta.ility condition for the frozen system. a.computer simula.ion is conducted. a.sta.ility index is defined using the da.ping ra.ios. The rela.ionships between the system sta.ility a.d the sensor loca.ion a.d feedba.k ga.n a.e investiga.ed.
