The self-tuning regulator (STR) is a popular adaptive control algorithm. A high-performance computer is required for its implementation due to the heavy online computational burden. To extend STR for more real-time applications, a parallel hardware implementation on a low-cost reconfigurable computer is presented. The hardware was incorporated with multistage matrix multiplication (MMM) and trace technique to enhance the processing speed. This design was deeply pipelined to achieve high throughput. The algorithm was prototyped on a Xilinx field-programmable gate array (FPGA) device with a maximum operating frequency of 210.436 MHz. Application-specific integrated circuit (ASIC) implementation of STR was reported.
