英文摘要

      In this paper，two new square-root algorithms to solve the LQ optimization problems for mul-tiple input and single input plants are proposed based on the QR decomposition，Fadeev algorithm，least square-root inverse decomposition and matrix-matrix multiplier. The algorithms are more numerical robust and efficient to sysolic mapping and implemented by multiphase systolic arrays，which can offer the optimal feedback gain matrix and speed up parameter synthesis for controller. The processor utilization，the time-steps and the multiphase opereations are discussed.
