Robotic soccer has become an interesting and attractive platform for robotic experim ents and research．The dynam ic response feature of soccer robot is crucial to the overall system ． This paper is dedicated to improving the dynam ic response of robotic movement in small-sized ROBOCUP matches．Instead of the widely used single closed loop control system based on speed feedback，the authors apply cascade control system by introducing current feedback circuit to the single loop control system ．The outer loop is to regulate the speed of the whee1．The inner loop is to adjust the current flowing through DC-motor．the authors utilize this cascade system by DSP and choose the optimized control parameters of two closed loops based on the mathematical model of DC-motor． The step and pulse response of the proposed cascade control system is demonstrated using M ATLAB simulations．The results show that the response tim e can be greatly shortened and overshoots can be reduced．It is clear that cascade control system can improve
the dynam ic response of a soccer robot．

Piezoelectric micropump is divided into six functional blocks (or subsystems)：the bimorph subsystem ，the chamber，the inlet valve subsystem ，the outlet valve subsystem ，the inlet pipe subsystem and the outlet pipe subsystem．The models of the terminal behavior of the six subsystems were established，then the term inal behavior of the subsystems were analyzed．After these，the models were connected together as the model of the whole system．The behavior of the whole system can be obtained by analyzing the model．

The discussion was undertaken about the structural steel consumption affected in different rise／span ratio and different circumjacent／center rise ratio．The optimal calculation of folded plate type latticed shell was developed．considering the steel consumption as an objective function and the number of lattice and the thickness of shell as variables．By using exhaustion method and 0．618 method，some orthogonal folded plate type latticed shell supported on four points were calculated．The optimallattice number and shell thickness were obtained under the different span from 20—40 m ．The result can provide a valuable reference for the design of folded plate type latticed shel1．

In practical projects，while an asynchronous motor starting，the drop of voltage on the bus bar must be within the lim its which is stipulated by the national standard． By establishing a equivalent circuit and mathem atics deduction，a form ula，by which we can calculate the largest rated starting capacity that permitted，was obtained．A nd on the basis of the result，the largest rated power of a motor that perm itted on a variety of conditions can be determined．M eanwhile，several factors that change the final result were discussed，as well as the error due to the approximation．
