Abstract The carrier equipment base is installed on the carrier, and the carrier is caused by the shaking, which is easy to affect the normal operation of the carrier equipment。 Therefore, measures must be taken to isolate the movement of the carrier。 Parallel stab ilization platform is based on the Stewart Parallel mechanism is presented a for ship borne equipment provide stable working environment of the platform, through the implementation of active control of parallel mechanism of every branch, weakens the impact by the platform。 The platform remains in a relatively stable work condition, to ensure the normal operation of shipboard equipment。 According to this, the design of the control system of the 6-SPS composite stabilized platform based on the parallel mechanism isstudied。The contentof thisresearch isas follows:
First introduces the background and significance of the research, analyzes the stable platform research status and development trend, and introduces the stable platform sensor device; secondly it introduces working principle and main structure of the composite type stable platform 6-SPS, the overall design of the stabilized platform control system; then the hardware selection and control system thecircuit structures, and establish themodel of non-symmetrical cylinder driving system, simulation analysis of single channel system on the stable platform; finally the design of control strategy of stable platform, method is to adopt cross coupling control, to the simultaneous acquisition of the platform on the platform pose disturbance and signal control, and on this basis, design fuzzy PID controller forthe sixhydraulic branch。
The mechanical structure and control system of the stable platform is suitable for the working condition of the platform of the carrier stable platform。 The control system and thecontrolledobject havegood compatibility。
